Core Sorting Principle

The entire challenge revolves around a simple rule: you can only place a card on top of another card that shares its exact color. Starting with a messy grid of mixed stacks, your goal is to rearrange every card until each column contains only one hue. This straightforward constraint creates a satisfying puzzle where every move matters.

Controls and Interaction

Interaction is handled through a direct drag-and-drop system. You tap a card from the top of any stack, then slide it onto another stack. The game provides unlimited undo, so you can reverse any move without penalty. This encourages trying different sequences and learning from mistakes.

Puzzle Progression

The game offers a large set of levels that gradually increase in difficulty. Early puzzles use fewer colors and smaller stacks, making them quick to solve. Later stages introduce more hues and deeper piles, requiring more foresight. Each level feels like a fresh logic problem.

Visual Style and Atmosphere

The design uses bright, clean colors and a simple interface. Cards are clearly distinct, and the background remains uncluttered. This visual clarity helps you focus on the sorting task without distraction. The overall mood is calm and inviting.

Strategic Thinking

Success depends on looking ahead. A hasty move can trap a needed card under several others. Experienced players learn to clear one color at a time and keep multiple options open. The unlimited undo function is a tool for experimentation, not a crutch.
