Three puzzles a day

Today's three puzzles are waiting. Start the streak.
Three logic puzzles a day. That is the whole challenge — and it starts again tomorrow.
YOUR STREAK
Finish today's three puzzles and your streak moves up a notch. Come back tomorrow and it grows again. How far will you go?
NEW TO THESE PUZZLES? THAT'S PLANNED FOR.
Most logic apps hand you the rules and leave you staring at an empty grid. Here, before your first puzzle, each game shows you its method in three habits — the order you actually go about it. Then a coach walks the opening moves with you, naming the technique behind each one, so you recognise it on your own next time.
After that, the "Why?" button stays. It does not fill a cell for you: it explains the deduction that makes the cell certain, highlights what to look at, and lets you make the move yourself.
THE THREE GAMES
• Constellation — Place circles on a diamond board so that none touches another, not even diagonally. Arrows along the border tell you how many circles each line holds.
• Tandem — Sixteen targets, eight pairs of numbers. Each pair yields a sum and a product, both to be found among the targets. The sorted strip at the top tells you which numbers are in play.
• Futoshiki — One to five in every row and column, no repeats, respecting the "greater than" signs between neighbouring cells.
FROM EASY TO EXPERT
Four levels per game, all open from day one. Six hundred puzzles in total: enough to keep the streak going for a very long time.
EVERYTHING WORKS OFFLINE
The puzzles ship inside the app. Underground, in the air, out in the country: it all works with no network.
WHAT IT COSTS
Today's challenge is free. To carry on past it, a short ad reopens a puzzle — as many times as you like — or a single purchase removes the limit and the ads for good.
No ad ever shows up on its own: no banner, no interstitial, no screen on launch. The tutorial and the "Why?" button stay outside the quota: learning costs nothing.
No account required — signing in with Google or Apple only carries your progress to another device, and the game is whole without it.
COMFORT
Undo and redo without limit. Pencil marks for Futoshiki. Automatic crossing of neighbours in Constellation. Optional stopwatch, off by default, that keeps your best times. Light and dark themes. Ten languages.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
On tablets, the home screen, the opening screen and the settings no longer stretch across the full width. Content stays centred and reads at the size it has on a phone. The puzzle board still uses the whole screen.
