5. Scoring & Winning
A light blue square doubles the letter; a dark blue square triples the letter (Appendix 1). A light red square doubles the word; a dark red square triples the word (Appendix 1). Where a word crosse...
People often think they can double a word if it crosses over a light blue square for letters and then another dark red square for words, but actually, you only get the bonus from whichever is higher—so if your letter gets doubled by the blue square first, you can't count that second red square as part of the whole-word doubling.
5. Scoring & Winning
A game ends in one of two results: a win for one player and a loss for the other, or a draw (7.1, 7.1.1, 7.1.2). A player wins when the opponent resigns, with or without reason (7.2.1). A player wi...
People often assume that a game ends in a draw if both players are blocked, which is incorrect according to the rules; they actually specify a player wins under that scenario (7.2.2), not a draw. The confusion arises because this rule isn't explicitly stated and could be easily overlooked or misinterpreted as a draw condition.
5. Scoring & Winning
Two consecutive passes normally signal the end of the game (AGA Rule 9). The players then agree which stones on the board are dead (AGA Rule 9) — stones that could not avoid capture if play continu...
People often assume that if two consecutive passes happen in Go (AGA), it means play automatically ends without counting stones as dead, which is incorrect. The confusion arises because the official verdict specifies players must first agree on which stones are dead before deciding who wins based on those counts. People sometimes overlook this step and rush to declare a winner prematurely.
6. Results, Draws & Scoring
Checkmate ends the game immediately, provided the move producing it was legal (Art. 5.1.1). Resignation: a player who resigns loses immediately, unless the position is one in which the opponent can...
People often assume that if a player resigns during their opponent's move, they lose immediately without considering whether it would have been possible for them to win with optimal play. Actually, the resignation only results in a loss if no checkmate is feasible from the current position. This rule can lead to misunderstandings about when and why a game ends due to resignation.
Card Games
Combat Sports
4.4 Corner Judges and Review Jury
Historically, four corner judges sat at corners of the mat and scored techniques using electronic handheld devices. With the adoption of the full PSS (electronic trunk, head, gloves, and socks), th...
People often assume that a coach can signal for an IVR challenge at any point during the match, which is incorrect. Actually, the coach can only raise the designated signal card during a break in the action to request an Instant Video Replay challenge, as per the rule's stipulation.
5.3 Valid Scoring Areas
The two valid target areas are:
People often assume that if a Golden Round starts with neither competitor scoring, it automatically goes into sudden death until one does score, but actually, once the round begins, points can only be scored in specific areas like head and body targets, not just any part of the opponent's body. This leads to confusion about when exactly the sudden death rule kicks in.
5.5 Overtime
If the score is tied at the end of regulation, the match proceeds to overtime:
People often assume that overtime in wrestling means a sudden-death format where one wrestler wins by scoring first, forgetting that it's more about maintaining control for longer periods rather than just getting points quicker. The confusion arises because they overlook the fact that wrestlers can score multiple times during an overtime period, not just once like in a sudden death situation.
5.9 Challenge System
Each wrestler (or their corner coach) is entitled to one challenge per match. A challenge requests a video review of a specific call by a review jury. If the challenge is successful and the call is...
People often assume that a challenge in wrestling is as simple as raising your hand when you disagree with a call, but they misunderstand that each wrestler or their coach gets only one challenge per match, which can lead to strategic decisions about where and when to use these limited opportunities wisely.
6. Scoring
A critical distinction: In UWW freestyle, brief exposure of the back to the mat (even momentarily) can score 2 or 4 points. In NCAA folkstyle, near fall points require the offensive wrestler to mai...
People often assume that team scores are calculated based on how many matches each wrestler wins individually, thinking it's a simple sum of individual victories. However, the actual scoring system in NCAA Folkstyle wrestling at nationals is more complex: it’s determined by the number of wrestlers advancing to championship bouts and their final placements, not just the total number of victories.
Esports
6. Scoring & Victory Conditions
A team wins by destroying the enemy Nexus. There is no time limit; games continue until one Nexus is destroyed or a team surrenders.
People think that if a game drags on for hours without either Nexus being destroyed, it could potentially go into an endless loop of no winner. But actually, the confusion arises because once one team successfully destroys both enemy Naxxes and captures their own Nexus, they win immediately regardless of how long other games have been playing out.
6. Scoring & Victory Conditions
Terrorists: Plant and detonate the bomb, OR eliminate all CTs. Counter-Terrorists: Defuse a planted bomb, eliminate all Ts, OR let the round timer expire. First team to 13 rounds wins the map (MR12)
People often argue that if a match ends in a 12-12 tie after 13 rounds, they automatically win just by virtue of having more rounds played, which is incorrect. The confusion arises because the official rule specifies overtime at 6 rounds per side, not just continuing to play until one team reaches 13 wins, ensuring fairness and preventing teams from coasting to a win through sheer round count.
6. Scoring & Victory Conditions
Attackers: Plant and detonate the Spike, OR eliminate all defenders. Defenders: Defuse the Spike, eliminate all attackers, OR let the round timer expire. First team to 13 rounds wins the map
People often assume that defenders can win by simply defusing the Spike before time runs out, forgetting about eliminating all attackers, which is crucial for them to claim a victory. The confusion arises because they overlook the requirement of eliminating all attackers as well, leading to misunderstandings and disputes during matches.
6. Scoring & Victory Conditions
A team wins by destroying the enemy Ancient. Games have no time limit and continue until one Ancient falls or a team concedes.
People often think that if both Ancient heroes are destroyed at the same time, it's a draw, which leads to endless debates. Actually, the official verdict is clear: one team wins by destroying their opponent’s Ancient, and games continue until either Ancient falls or one team concedes, regardless of what happens with the other Ancient.

2.5 Suspension
The Next Gen car uses a double-wishbone front suspension and an independent rear suspension (IRS) — a significant change from the previous solid rear axle configuration. Suspension geometry adjustm...
People often assume that since NASCAR cars now have an independent rear suspension (IRS), they can simply adjust their rear tires like a stock car without worrying about handling changes, but actually, the complex geometry adjustments required for this new setup are crucial to maintaining optimal performance and stability under various racing conditions.
3.3 Start/Finish Line and Scoring Loops
The start/finish line is the official scoring reference for lap completion, race start, and race finish. Inductive scoring loops embedded in the racing surface transmit transponder data to NASCAR's...
People often assume that the inductive scoring loops are just for timing purposes and don't affect scoring directly, which leads to misunderstandings about their importance in determining lap completion and race results. The confusion arises because they see these loops as merely timing devices rather than integral parts of how race outcomes are officially recorded.
5.6 Overtime (Green-White-Checkered)
If a caution is displayed within the final two laps of a stage or the final two laps of the race, NASCAR will attempt to complete the event under green-flag conditions using the Green-White-Checker...
People think that if a caution is displayed in the final two laps of a race, it's automatically over and they have to use overtime, but actually, the rule only kicks in if there are still at least 20 seconds left on the clock when a caution comes out, ensuring some racing time remains before deciding on overtime.
5.9 Race Suspension and Postponement
NASCAR Race Control may suspend a race at any time due to inclement weather, track conditions, or other safety concerns. A race is considered official after the completion of 50% of the scheduled r...
People often assume that if a race is suspended due to weather before 50% of the distance has been completed under green flags, it's automatically called off entirely. But actually, as long as at least half the scheduled distance was run under clear conditions (green flag), NASCAR considers the race official regardless of what happens later in poor weather.
5.9 Race Suspension and Restart — Sporting Regulations, Article B5.14
The Race Director may suspend the race (red flag) if the track is blocked or conditions are dangerous. Red flags are shown at the start/finish line and at all marshal posts, and the message "RED FL...
People often assume that a red flag means all cars must immediately stop at their pit boxes, which leads to arguments about who stopped first and second. However, the actual rule states only that drivers show the red flag signal as instructed by the Race Director, allowing them to continue on if conditions permit without stopping, thus avoiding unnecessary grid penalties or disputes over timing.

3.5 Fair and Foul Territory (OBR Rule 2.01, Definitions)
Per the OBR Definitions of Terms, "Fair Territory" is that part of the playing field within and including the first base and third base lines from home base to the bottom of the playing field fence...
People often think that fair territory only includes the area between the foul lines and the outfield fence, forgetting about the infield part of it. But actually, the definition extends all the way from home plate to the bottom of the fence along both base paths, making the confusion arise because they overlook this crucial detail in the infield.
4.3 Offside Rule — Men's Field
At all times during play, each team must have a minimum of:
People often assume that offside in lacrosse is just like in soccer - only one player can be behind the defensive line at a time. But actually, it's more complex; the 4.3 Offside Rule for men’s field states you can have up to three players on either side of the attack line as long as they're not all directly behind it, leading to confusion about how many and which players are allowed where.
5.8 Overtime
If the score is tied at the end of regulation in men's field lacrosse, a sudden-victory overtime period is played. The first team to score wins. Overtime periods are typically four (4) minutes long...
People think that if a game ends scoreless in regulation, it automatically goes into sudden-victory overtime with no extra time added, but actually, teams must play at least 5 more minutes of full regulation before considering overtime. This often leads to confusion about when the actual overtime period begins.
Tile Games
5. Scoring & Winning
Three conditions must all hold to declare "Hu": the hand is one of the permissible structures; its fan total at least 8 points; and the winning tile was obtained by a permitted method (3.9.1). The ...
People often argue that they've achieved a "Hu" when their hand meets all conditions except for the eight-point minimum. They mistakenly believe that as long as their structure is valid and they have at least 8 fan points, it's enough to declare a win, overlooking the crucial last condition about obtaining the winning tile through a permitted method.
5. Scoring & Winning
All players are responsible for each hand being scored correctly and to the maximum; each player counts their own han and minipoints and others must correct mistakes (4.1). Count han first — the ya...
People often assume that counting ura dora for riichi hands is a straightforward addition to han points, forgetting that it's only applicable in those specific situations. This leads to misunderstandings about when exactly to apply this scoring detail and can cause disputes over whether certain plays should have been counted as riichi at all.

3.3 Penalty Loop and Stadium
Penalty loop: 150 m (492 ft) circuit located adjacent to the shooting range. Athletes ski one loop for each missed target (in Sprint, Pursuit, Mass Start, and Relay events). Completing one loop add...
People often assume that manual backup targets are only used as a last resort in case of electronic system malfunctions, forgetting that they're always present for every shooting event, ensuring accuracy regardless of technical issues. They overlook the fact that these backups are an integral part of the rule, not just a fallback option.
3.4 Player Benches and Penalty Box
Team benches: Located on the same side of the rink, one for each team, separated by the penalty boxes at centre ice.. Penalty boxes: Two boxes at centre ice (one per team) for penalised players. A ...
People often assume that the safety glass extending above the boards is there purely for aesthetic reasons, when in reality it's crucial for player safety during rough collisions or accidental falls off the bench. They overlook how this glass can prevent serious head injuries by acting as a barrier to incoming pucks and other players.
5.2 Offside
An attacking player may not precede the puck into the attacking zone (beyond the blue line). If an attacking player's skates are in the attacking zone before the puck completely crosses the blue li...
People often assume that offside is called based solely on a player's position in the zone before the puck crosses the blue line, but actually it’s about whether their skates are in the zone when the puck leaves the defense. They overlook the crucial moment when the puck moves past the line, focusing instead on where players were at any point during the play.

Concussion Protocol
The NFL operates one of the most comprehensive concussion protocols in professional sports. Any player suspected of sustaining a concussion is immediately removed from the game and evaluated by the team's medical staff in the sideline medical tent or locker room.
People often assume that if a player is removed for suspicion of concussion, they are immediately sent home or treated by medical professionals in their own team's locker room, but actually, players suspected of having concussions are evaluated by the team’s sideline medical staff and then transported to an off-site facility equipped for handling such emergencies.

2.2 Boots and Bindings
Ski boots must not exceed a sole length of 43% of the competitor's body height. Maximum boot sole height is 45 mm (1.77 in) at the toe and 55 mm (2.17 in) at the heel, measured without the binding plate.
People often assume that the sole length limit is purely about safety, thinking it's to prevent boots from slipping off their feet during turns. However, the actual intent of limiting boot sole height to 45 mm is more about aerodynamics and minimizing drag, ensuring skiers can maintain optimal speed and control without excess weight or bulk affecting performance.
