Zigsum

Drag a line through numbered tiles. The chain commits the moment its sum hits the target, and the board is a partition — every tile belongs to exactly one chain, so a wrong early chain is what strands the rest.

How the daily works

• Everyone gets the identical board. It comes from the server, and nobody can see tomorrow's.
• Tap a committed chain to take it back — the board keeps them dimmed so you can read back what you did.
• Scores are checked by replaying your moves on the server, so a leaderboard is what happened.
• Your name is picked for you from your device. No account, no email, nothing to fill in.
