## What is Stacklear?

Stacklear is a color block merge puzzle for one hand. Drag blocks onto an 8x8 board, join matching colors, level them up, and clear lines for big combos.

HOW TO PLAY
- Each turn you get 3 blocks. Drag and drop them anywhere on the 8x8 board.
- Place same-color blocks next to each other to merge them into a higher level.
- Level 1 blocks merge in groups of 3. From Level 2 to Level 5, just 2 matching blocks merge.
- Merge two Level 5 blocks to clear a full row or column.
- New merges can trigger chain merges for a higher combo multiplier.

OBSTACLES THAT KEEP YOU THINKING
- Stone: can't be merged. Merge right next to it to break it.
- Ice: frozen color blocks. A merge next to the ice thaws it so it can merge again.
- Bomb: counts down with every block you place. Clear it with a nearby merge or a line clear before it reaches zero.

TWO WAYS TO PLAY
- Levels: 500 levels with goals like reaching a score, merging up to a target level, or clearing lines. Boss levels mix several goals.
- Endless Mode: no goal, just you and the board. Keep merging and chase your best score.

MADE FOR SHORT SESSIONS
- Portrait layout built for one-handed play.
- Levels are read with numbers and shape marks, not just color shades.
- Reduce Motion option in Settings to tone down visual effects.

Easy to learn, with more to plan the further you go. Merge, level up, and clear the board in Stacklear.
