A matrix of 6x6 cards are set. The initial deal has 6 cards face up, SW to NE.
You are dealt 7 cards. You must pick one card to nominate the trump suit, with 6 cards remaining to play during the round.
Place a card at the edge of the GRID to challenge along a row or column, to the opposite edge. Eg: Placing card on the right edge, row 3, will play from column 6 to column 1, along row 3.
Each card along the challenged line will be flipped until:
- The card flipped matches the suit you played, if the card rank (Aces high)...
- is less than your card, you win the trick
- is more than your card, you lose the trick.
If no card matches your suit...
- If the line contains any trump suit card, the lowest card is used, you lose the trick.
- If the line containes no trump suit, you may pick any card to remove from the line, you win the trick.
After 6 rounds, scores are tallied and the GRID is refreshed. Any lines with only face-up cards are cleared. You are dealt 7 cards and play continues as before.
If the GRID scores 11 (or 21 in beginners mode), you lose.
If you score 31 and the GRID has not scored 11 (or 21 in beginners mode), you win.
Note that scores are tallied after a 6-trick round is complete, not mid round. Its possible to score 31, but lose to the GRID scoring 11 in the same round.
