Plusible

Plusible is a number-path puzzle you play with one thumb. Every board is a grid of numbers and a target. Trace a path from square to square so the numbers along it add up to exactly the target. That is the whole rule. There is no tutorial to sit through — the first board teaches you in about ten seconds. Then it gets interesting. Multiplier squares double what they touch. Blockers cut the grid apart. Locked squares must be crossed. The grid grows, and the number of valid solutions shrinks — until only one path is left and finding it feels like solving a small, private mystery. FOUR WAYS TO PLAY Daily Path — one puzzle a day in three difficulties, identical for every player in the world. Build a streak. Share a spoiler-free result card. Endless Journey — a difficulty curve that keeps rising. Every level is generated deterministically and verified solvable before you ever see it. Time Attack — ninety seconds. How many paths can you find? Zen — no timer, no streak, no score. Just you and the grid.
