+## Manual roulette checklist
+
+1. `play roulette` shows the balance, chip size, empty bets, and controls.
+2. `R`/`B`/`E`/`O` add one chip; digits + Enter add a number; `C` clears;
+   `+`/`=`/`-` change the chip size.
+3. Space scrolls the wheel under a fixed ball marker and ends on the winning
+   number.
+4. Check a split result:
+   - `17 black odd`: black+odd pay, red+even lose, straight 17 pays 36x.
+   - `0`: all outside bets lose; a straight 0 pays 36x.
+5. The result board shows the winning number/color/parity, the payout, and the
+   new balance. The next spin reuses the placed bets.
