Basic captures, special rules, and chain reactions.
You and your opponent each start with five cards. Take turns placing one card in any empty cell. A randomly chosen player goes first.
Each card has a top, right, bottom, and left value. When you place a card, its sides challenge the touching sides of adjacent cards. A strictly higher value captures an enemy card. Equal values do not capture under the basic rules. A means 10.
The match ends after nine placements. Every card you control counts for one point, including the unplayed card in hand. The scores always add up to 10. More points wins; 5–5 is a draw.
Both five-card hands are visible. Closed hands hide unplayed cards; Three Open reveals three randomly chosen cards in each hand at the start and keeps the other two hidden.
Both players can see every card in both hands.
Your hand remains visible to you in every mode.Match the touching values on at least two adjacent cards to capture the matching enemy cards. Friendly cards can help make the match.
Example: 4 meets 4, and 7 meets 7.Blue to play. Place your card in the center.
Add each touching pair. If at least two pairs have equal sums, capture the matching enemy cards. Friendly cards count here, too.
Example: 3 + 6 = 5 + 4.Blue to play. Place your card in the center.
Cards captured by Same or Plus attack adjacent enemy cards using the normal higher-value rule. Each new combo capture can continue the chain. Ordinary captures do not start combos.
