Take turns removing 1–3 stones from one of three piles over ten matches. In the first five, taking the last stone wins; in the last five, taking it loses.
W/S selects a pile, A/D selects how many stones to take, and RETURN takes them. You cannot take from several piles in one turn. Your opponent also chooses winning moves when available, so plan the shape of the piles you leave behind.
Directions work on the keyboard or pad; the pad button also acts as RETURN. SPACE opens confirmation to restart this stage. NO is selected initially. Choose with A/D, confirm with RETURN, or cancel with SPACE. Play pauses during confirmation. CTRL+C returns to BASIC.
Stones sit on shelves with visible depth. Selected stones fly off the board one at a time. Your move and the opponent's move have separate sounds and pauses; the result appears after the last stone can be seen leaving. Wait for animations to finish before pressing again.
LAST STONE WINS / LOSES states this match's rule. TAKE is the chosen amount, and RIVAL TOOK is the opponent's previous amount. Arrows mark the stones you are about to take.
