How to play

Five quick steps. You'll have it after one round.

Press & hold a dot, drag to another, release — three lines make a triangle

1

Roll the dice

On your turn, tap the dice. The number you roll is how many lines you can draw.

2

Connect two dots

Press & hold a dot, drag to another dot, then release to draw the line. Lines can't cross or clip another dot.

3

Changed your mind?

While holding, release on empty space instead of a dot — the move is cancelled and nothing is drawn.

4

Shape a triangle

Connect dot 1 to dot 2, dot 2 to dot 3, then close it back to dot 1. The triangle fills with your colour and scores a point.

5

Most triangles wins

The round ends when no more lines can be drawn. Whoever claimed the most triangles wins.
