Individual hand: bids describe only your own dice, turning it into a pure poker-dice bluff.; Exact call ("spot on"): claim the bid is precisely right — if so, everyone else loses a die instead.; Ones not wild: removes the wild rule entirely and makes bids much easier to break.
Why people argue about this
People often assume that in "Exact call" (claiming a bid is precisely right), they can bluff their opponents into thinking they have more dice than they actually do, which leads to confusion because this isn't allowed; instead, it's meant to make the game harder by requiring players to be spot-on with their claims.
