Each Crown earns 3 Roll coins for your next roll, each Diamond earns 2 (up to 7). Two Diamonds count as one Crown. Every roll banks one less than your Crowns, so 2 Crowns bank 1 and 5 Crowns bank 4. A Crown or Diamond in a Crown Zone counts double.

Every cube must reach the near Silver line. Landing on the line counts; landing below it or rolling off the table is a fault, and that cube gets a second serve. Fault again and that cube is lost for the roll. You earn one bonus cube for every 5 rolls: 1 at roll 5, 2 at roll 10, 3 at roll 15, 4 at roll 20, 5 at roll 25, and so on.

All Voids on your first roll ends the game. Later, trade one Bank coin for a rescue roll: 2 cubes, 3 once you hold 5 Roll chips, 4 at 10, 5 at 15, 6 at 20, 7 at 25. Out of Bank coins and still Void, you're out.

Win chance: after every roll, the game plays out 4,000 simulated games from your exact spot (your Bank, your cubes, your bonus) using the same odds as your real rolls, and shows how many of them bank seven.
