Players take turns placing cards on a 4×4 board of 16 squares. When all 16 are filled, the game ends and whoever holds more cards wins.
Any card left unplayed still counts as yours.

The final move always falls to the player who goes second, so the first player is dealt 9 cards and the second 8. 17 cards are contested in all — so a draw is impossible.

BASIC — compare the numbers

Where two cards touch, the higher number flips the other.
Only the touching sides matter; the other three numbers do nothing.

SAME — two identical sides

If the touching numbers are exactly equal in two or more places, you take those cards regardless of size.
A single match does nothing.

PLUS — two equal sums

If your number and your opponent’s add to the same total in two or more places, you take those cards too.

WALL — the edge counts as A

The board’s outer wall can be treated as A (=10) when checking for SAME.

COMBO — captures cascade

Cards taken by SAME or PLUS then capture their own neighbours by ordinary comparison.

COLOURS — what the squares mean

Gold = how many you would take / Purple = a special capture will fire / Green = playable, but takes nothing
