Dodeku

About Dodeku

Dodeku is made and edited by Lukas Stanley of Fox Point Games, the studio behind Agent Caesar, Zaggle and Wordsmyth. Each puzzle is a 4x4 grid. Some squares are blacked out, a few numbers are given, and sums sit alongside the rows and columns. You have a tray of number tiles and must drag them into the empty squares so that every line adds up to its target.

The game counts your moves, and you can recall all tiles to the tray or unlock tiles to rearrange them. Puzzles run in a dated sequence that began with Dodeku #1 on 29 January 2025, so every player gets the same one each day, and the archive lets you go back to earlier numbers. There is also a printed book of puzzles.

Fox Point Games is free and has no ads, supported by optional memberships. You can sign up for a daily email reminder when the new puzzle drops. It suits people who like Kakuro or KenKen but want something that takes a few minutes.

How to play Dodeku

1. Press Play to open today's grid.
2. Look at the given numbers, the blacked-out squares and the sums beside each row and column.
3. Drag number tiles from the tray into empty squares.
4. Adjust until every row and column adds up to its sum; use Recall all to start over.
5. Finish in as few moves as you can and share your result.

Tips

• Start with lines that have only one empty square: the missing number is the sum minus the rest.
• Use the largest and smallest tiles first, since they fit in fewest places.
• Blacked-out squares shorten lines, so short lines with big sums narrow things quickly.
• Check a placement against both its row and its column before moving on.
