> Match free tiles to clear the stack.

Match free tiles and clear the stack. Today's stack is the same layout for everyone. Practice opens taller stacks as you clear them.

- Play: https://sidekickarcade.com/play/mahjong-solitaire/ (in the browser, phone or computer, free, no sign-up needed)
- Neighborhood: [Puzzle Park](https://sidekickarcade.com/category/puzzle/index.md)
- Controls: Tap two matching tiles, or arrows and Space
- Best on: portrait screens
- Coins for goals: 3 per 1 stars, up to 9 a run

## How to play

1. Tap a free tile, then the one that matches it. A tile is free when one side is open and nothing sits on it. On a keyboard, arrows move and Space selects.
2. Coins, sticks, ranks, winds and discs match only the same tile. Any two blossoms match each other, and any two seasons match each other.
3. Hint shows a free pair and costs a star. Undo puts the last pair back and does not cost a star.
4. Three stars means a clear with no hints, inside the time. Today's stack is one layout for everyone. Pause stops the clock.

## Tips

- A tile is free when nothing sits on it and at least one side is open.
- Blossoms match any blossom, and seasons match any season. Everything else matches only itself.
- Hint outlines a free pair and costs a star. Undo is free.
- Three stars means no hints, inside the time. Pause stops the clock.

## Questions

### Is it free?

Yes. It is free in the browser, with no download and no sign-up needed. Coins are for fun and can never be bought.

### Is today's stack the same for everyone?

Yes. Today's stack is one layout, from the date. Practice stacks are your own, and they get taller as you clear them.

### What earns three stars?

Clear the stack with no hints, inside the time for that size. A hint still clears the stack, for one star. Undo does not cost a star. Pause stops the clock.

### Can I play on a phone?

Yes. Tap a free tile, then the matching one. Hint and Undo sit under the stack, so they never cover a tile.
