Thricewise

This is a fast playing game for the Decktet game system.

Every turn, you try to add one card to the grid. You score a point each time your card makes three in a row. Threesomes must be in rank order, all be of the same rank, or share a suit symbol. Players select their cards simultaneously, however, and the perfect spot for your card might be gone by the time you get to play it.

Rules are on the Decktet Wiki and as a PDF.
