Tally

Tally is a daily logic puzzle where you’ll connect up to four numbers that add up to 10. Every number on the board must be used, and there’s only one solution that fills the grid without leftovers.

How it works:

• Draw a path connecting 2–4 numbers.
• If the total equals 10 and allows the board to be completed, the group locks in.
• Some groups that add up to 10 are not permitted because they would prevent the board from being completed.
• Paths of length 5 or more are invalid.
• You must fill the entire board using valid 10-sums.
• Make 5 mistakes and it’s game over.

Why we like it:

• ✅Feels like math + pathfinding + puzzle design in one.
• ✅Very little guesswork, deduction is the way through.
• ✅Fast, satisfying daily flow with a clean aha moment.

Hint: Start filling the board from the outskirts and work your way in. Look for “forced friendships”: a 9 next to only one 1 or any unique 8+2 pairing.
