Place one line in your own colour on an empty segment.
Score triangles by colour majority, as in Level 2.
Each triangle gives 1 point.
Each completed triangle gives the non-scoring player 1 Yra Stone, up to 3.
At the start of your turn, return 3 Yra Stones for one bonus line before your normal move.
Complete a triangle with a normal move to play again, even if the opponent scores.
Unused Yra Stones give no points. Most points wins.
