How it works

A word appears with some letters hidden — only the first and last letters are given. A definition hint is available if you need it.

A rack of tiles appears below — the correct letters shuffled with decoys. Tap to fill the blanks one by one.

Tap the wrong tile and it bounces back with a 5 second time penalty. The hint also costs 5 seconds. Choose carefully.

Your final time including all penalties is your score. Lowest score wins. Come back every day to build your streak.

A number pattern appears with one number missing. Patterns range from simple sequences to Fibonacci, squares, and more.

Four possible answers appear below. Only one is correct — the others are plausible decoys designed to catch you out.

Pick the wrong number and it flashes red — adding 5 seconds to your time. The hint also costs 5 seconds.

Puzzles rotate through easy, medium and hard — randomly spread through the week. Easy days are great for streaks, hard days test your limits.

Each day a new code is generated. You have 6 guesses to crack it. Enter any 4-digit number as your first guess.

Each digit gets feedback: a green ✓ badge means right digit, right position. An amber dot means right digit, wrong position. Grey means the digit isn't in the code at all.

Use the clues to eliminate possibilities. Fewer guesses = better score. Time also counts — solve it fast for a higher ranking.

1 guess = 10,000 base points, 2 guesses = 20,000, etc. Seconds are added on top. Lowest score wins — fewer guesses beats faster time.

A shape appears with a target fraction — like "split this circle into 50%". Three shapes per day, each with its own target.

Drag a straight line across the shape to cut it. You can re-aim before committing — but there's no error readout to guide you. Trust your eye.

Submit your slice and see how close you got. Your error across all three shapes is added up. Smallest total error tops the leaderboard.
