Cugi — Can U Guess It?

Set riddles, crack others, and race your friends through a live quiz.
You play both sides.

Free to play. No purchases, no paywalls.

Everyone plays both sides

Be a Knower

Set a riddle — a hidden number, a secret word, or a free-text brain-teaser — and score points every time someone takes it on, most of all when they crack it.

Be a Guesser

Crack the open challenges other players have set. The fewer guesses you spend, the more points you bank — and be the first to solve one for a bonus.

What's in the game

Three riddle types — Numbers, Words, and free-text puzzles, so it never gets stale.
A new Riddle of the Day everyone can play — see who cracks it fastest.
Real head-to-head scoring — your points come from real players you outwit.
Quick rounds that fit a coffee break, a commute, or a queue.
Leaderboards to climb, and a streak to defend.
Light and dark themes.
