Idle Marble Run

Drop a marble. Watch it fall through the pegs, light up every bumper it touches, and turn each bounce into gold. Two marbles of the same kind that meet become one bigger marble, worth far more than the two that made it. That single rule is the whole game, and it never stops paying off. MERGE YOUR WAY UP Every merge unlocks a richer marble. Grey, gold, ruby, sapphire, emerald: the ladder keeps going, and so do the numbers. THE BOARD KEEPS EARNING Close the app and the marbles keep working. Come back to a pile of gold waiting to be claimed, and double or triple it on the spot. FIVE SPECIAL MARBLES FIREBALL destroys bumpers in a single hit. SNOWBALL grows with every bounce. RAINBOW is pulled toward the pegs. SHADOW clones itself on impact. BUBBLEGUM sends bumpers flying. AND PLENTY MORE A cannon that fires marbles on its own. Bonus letters scattered across the board. A gallery to fill with every marble in the game. Achievements, levels, and a cloud save that carries progress from one device to the next. No energy bar, no lives, nothing to unlock with a timer. Just bouncing physics, gentle celebrations, and numbers that always go up. Idle Marble Run is free to play. It contains ads and optional in-app purchases, and any purchase removes the ads for good.
