 ## 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
+1. `play roulette` draws the full felt: 0, the 3x12 numbers, dozens, columns,
+   and the six outside cells, with the cursor on number 1.
+2. Arrows move the cursor. On the numbers the highlighted cells show the bet:
+   one number (straight), two (split), four (corner). Down leaves the felt into
+   the dozens, then columns, then outside; Up walks back.
+3. ENTER places the chip where the cursor is; `C` clears; `+`/`=`/`-` change the
+   chip size. The bets line lists every chip and the total.
+4. 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. Numbers are color-coded: red numbers red, 0 green, black default. Check the
-   bets line, the rolling strip, and the winning number.
-6. The result board shows the winning number/color/parity, the payout, and the
-   new balance. The next spin reuses the placed bets.
+5. Check the payouts:
+   - a straight pays 36x, a split 18x, a corner 9x;
+   - a dozen or column pays 3x;
+   - an outside bet pays 2x;
+   - `0` loses every outside bet, both dozens and every column, and pays a
+     straight 0.
+6. The result line names the number, color and parity, the total returned and
+   the profit. The next spin reuses the placed chips.
+
+## Manual terminal size check
+
+1. Start the client in a terminal smaller than 80x24: it must print
+   `zagan.bet needs a terminal of at least 80x24 cells` and exit without
+   switching to the alternate screen or raw mode.
+2. At 80x24 every game board (slots 10 lines, roulette 12, blackjack 6, crash 6)
+   must fit without wrapping.
