LOOP is a small set of three free daily brain games you play right in your browser — Color Hunt, Daily Number, and Merge Drop. No app to install, no account to create, no email to hand over. Open the page, play, done.
Each game is built to fit into a spare minute. The idea is simple: come back once a day, take on the same challenge everyone else is facing, and keep a little streak alive. There's no campaign to grind through and no pile of levels waiting to guilt you. Just one fresh board a day, three different flavors of it, and a worldwide leaderboard if you feel like measuring yourself against the rest of the room. Everything runs on your phone, tablet, or computer in any modern browser.
The word "daily" does real work here. Every game generates its board from the date, so everyone in the world gets the exact same challenge each UTC day. When the clock ticks over to a new UTC day, all three games reset to a brand-new board at the same moment. That shared-board design is the whole point: your result is a fair comparison against everyone else playing the same day, and it's easy to screenshot or describe to a friend so they can try the identical puzzle.
The three games handle attempts a little differently, on purpose:
Across all three, playing on consecutive days builds a streak. The streak rewards showing up, not grinding — a minute a day is enough to keep it going.
A reaction-and-attention game. The board fills with tiles of a single color — except one tile is a slightly different shade. Tap the odd one out before the timer runs out. Clear it and the next round starts immediately: the grid grows and the shade difference shrinks, so it gets harder fast. Tapping correctly without a miss keeps a combo going, and a clean run multiplies your points far beyond a cautious one. It may help you practice quick visual scanning under time pressure.
Play Color Hunt → · How to playA logic puzzle in the spirit of code-breaking. Crack the hidden 4-digit number in 6 tries — though roughly one day in seven is a tougher day that gives you one fewer. After each guess, every tile gives you a clue: green means the right digit in the right spot, yellow means the digit is in the number but in a different position, and gray means it isn't in the number at all. Read the clues, rule out what you can, and close in. It's the same number for everyone, one solve a day — so a clean deduction is worth bragging about.
Play Daily Number → · How to playA physics merge game. Drop balls into the bin, and when two balls of the same size touch, they merge into the next size up. The balls roll, settle, and pile under real gravity, so where you drop matters as much as when. Chain merges to climb the score — but the catch is the line near the top: let the pile cross it and the run ends. Easy to learn, genuinely hard to stop playing, and the daily board means everyone's working the same stack.
Play Merge Drop → · How to playEach game has its own worldwide daily leaderboard. For the score games, only your best run of the day counts — so a later attempt that pushes your number higher simply replaces a weaker one, and your latest mistake never drags you down. For Daily Number, your single solve is what posts. The board shows roughly where you land — your rank, the share of players you're ahead of, and your top-percentage for the day.
Posting a score is optional. You can stay a Guest, or add a nickname so your result shows on the worldwide board, and you can change that nickname anytime. To keep the boards friendly, nicknames are moderated. None of this requires an account — your nickname and progress live on your own device.
LOOP is completely free, with nothing to buy and no premium tier. It's supported by ads, which is what keeps the games open to everyone with no paywall. Your progress and settings are saved locally in your own browser, not on a server tied to a login.
