Block sort
Blocks of different colours are mixed across columns. Move the top block onto another column — if there is room and its top is the same colour (or it is empty). Make every column a single colour.
How it works
- Everyone gets the same puzzle — fastest wins. Three puzzles, each with more colours.
- Tap a column — it lifts; tap another — the block moves.
- Stuck — "Restart" (the clock keeps running). Whoever runs out of time is ranked by sorted columns.
Tips
- An empty column is gold: don't fill it without a reason.
- Start with the colour that is most often on top.
