DayDuel
What is DayDuel?
DayDuel is a free daily puzzle game that combines two different challenges: a visual grouping puzzle and a line-drawing puzzle. Each day brings a fresh set of puzzles, and no account is needed to play.

The decoy-link twist is a sharp fairness test, but I'd want more evidence that the line puzzle's difficulty scales cleanly for veterans.

Perfect for a coffee-break duel—two quick brain tickles with no signup friction, though I'd love a hint when I'm stuck.

A daily duel you can take anywhere, but the picture groups could use a stronger sense of place to make the travel worth it.
How to play DayDuel
In the first puzzle, find four groups of three pictures that share a connection, while avoiding the one deliberately misleading decoy link. In the second puzzle, draw a single line that passes through every square on the board.
Tips & strategy
- Look for obvious visual or thematic similarities in the picture puzzle before considering more abstract connections.
- Remember that one of the displayed options is a decoy — if an image seems tempting but doesn't fit a clean group of three, set it aside.
- Try grouping the strongest pair first, then check whether a third image completes that set.
- For the line puzzle, plan a route that covers all squares before you start drawing, and avoid trapping empty squares in enclosed areas.
- If you're stuck, switch between the two daily puzzles and come back with fresh eyes.
