A small game about colours that deepen. Tip the board and let the blocks fall. When two identical ones meet — same colour, same number — they merge into one a shade deeper. Three in a row jump two shades at once. It sounds simple. Then you find out that a blue 3 and a blue 1 do nothing together, and you start planning ahead. DAILY CHALLENGE One fixed board every day, the same one for every player. The goal is set, the moves are limited. Match the best possible solution and you earn three stars — and that solution is not an estimate, it is computed down to the last move. Share your result if you like. It shows moves and stars, never the route, so nobody's tomorrow gets spoiled. A STREAK THAT SURVIVES A WEEKEND Two freezes protect your streak. Miss a day and a freeze covers for you. Play five days and you get one back. You don't have to take your phone up a mountain to keep it alive. LEADERBOARDS The daily table resets each day and shows who solved it in the fewest moves. Alongside it run a lifetime collection of stars and your best endless score. SMALL THINGS THAT MATTER • Every tile carries a number, so colour is never the only signal. • Red and green never appear together in the palette. • The game won't interrupt your music and respects the silent switch. • Works offline. The daily puzzles ship inside the app, not on a server. • One undo, and one shuffle per game when you're truly stuck.
