Three cards. Every feature must be all-same or all-different.
The field always keeps at least two live sets (four on 4x4) — more sets on the field mean a
lower cap, and points bleed the longer you hesitate.

HOW TO PLAY
▲ THAT'S A SET
3x3 FIELD — 9 cards, 3 features: shape · fill · colour. Quick rounds, zero clutter.
4x4 FIELD — 12 cards + a 4th feature, count (1-3 glyphs). More cards, harder hunt.
Select 3 cards — if every feature is all-same or all-different, it's a set.
PAYOUT CAP — a board with 2 live sets (4 on 4x4) pays up to 300. Each extra set on the board cuts -40, floor 100. Only what's on the board counts.
STAY SHARP — payouts bleed down to half the cap while you think (12s on 3x3, 24s on 4x4). Freeze up and your streak dies.
EVERY REFILL = ≥ 2 sets (4 on 4x4) guaranteed. No dead boards.
