How to Play Square It
Square It! is played on a 5×5 dot grid with 25 dots. Players take turns drawing one line between any two valid dots.

- Tap a second dot to draw the line.
- Form a square — 4 equal sides, 4 right angles — to score a point.
- Extra turn — completing a square earns an immediate bonus turn.
- Think geometrically — squares can be rotated at any angle!

Square It Strategy Tips
- Think rotated — the most powerful squares are diagonal ones that opponents miss.
- Avoid 3-sided traps — don't be the player who completes the third side of a square, giving your opponent the point.
- Overlapping awareness — one line can complete multiple squares at once. Set these up!
- Count the edges — near end-game, calculate which moves cost you the least squares.
