Triangle Capture

First, drag the triangles to arrange the board however you like, then press Start. Then players take turns: on your turn, tap a free corner of one triangle, then a free corner of another — the line finds its own way around everything in between, joining exactly those two corners. Which corner you use matters, since it decides what's still reachable later. A line may never cross another line, the same two triangles can't be connected twice, and each triangle holds at most 3 lines (one per corner). Whoever draws a triangle's 3rd line captures it, and it fills with their colour. When there's no legal connection left anywhere on the board, the game ends — most triangles wins. Some triangles usually end up boxed in and captured by nobody; that's fine.
