About Box Claim
The classic pen-and-paper duel on a grid of 25 dots. Take turns drawing one line between neighbouring dots; whoever draws the fourth side of a box claims it and moves again. The AI grabs every free box and avoids setting up chains for you, so the endgame is a real fight over who has to open the long chains.
How to play
- Tap the gap between two neighbouring dots to draw a line.
- When your line completes the fourth side of a box, you claim it with a star.
- Claiming a box gives you another turn straight away.
- The AI answers with coral lines and claims boxes with an ✕.
- When all 16 boxes are taken, the player with more wins.
Objective
Claim more of the 16 boxes than the AI.
Tips & strategy
- Never draw the third side of a box — it hands the AI a free capture.
- Count the safe moves left: the player who runs out first has to open a chain.
- When you do have to give boxes away, open the shortest chain.
