Tri-Ominoes
A triangular tile-laying game of matching numbers and growing tessellations.
How to play
- 56 triangular tiles, each with a number 0–5 at every corner. Each player starts with 7.
- Place a tile so each corner that meets an existing tile shares the same number — both along shared edges and at every shared vertex.
- Score the sum of the placed tile's three corners.
- Bridge bonus: +40 if the tile shares all three edges with existing tiles.
- Hexagon bonus: +50 each time the placement completes a 6-triangle hexagon around a vertex.
- If you can't play, draw a tile (−5 penalty). If you still can't, your turn passes.
- Game ends when a player empties their hand (+25 bonus + opponent's hand value), or both players pass with the draw pile empty.
