How it works

Choose from a hand of numbered tiles. You start with four.
Each tile you select adds to the current stack.
Reach exactly 21 to clear the stack and score.
Going over 21 is a strike.
Three strikes end the game.
Clearing stacks in a row builds a streak, and each clear in a streak is worth more.
