MergeLab
Merge two same-tier items side by side into a higher tier and explore a 15-tier chain from Quark to Cosmos. Build cascading combos, keep cells free, complete missions and unlock the Codex. Play Challenge (you can lose) or Zen (relaxed, no game over).
目标
Merge two items of the same tier that sit next to each other (horizontally or vertically) to create a higher tier. Climb the 15-tier chain and unlock the whole Codex. Score as high as you can.
操作
- Tap an item to select it, then tap an adjacent same-tier item to merge
- Or drag an item onto an adjacent same-tier item
- The 🔍 button opens the Codex of discovered tiers
- The ✂ button removes one item (limited uses) to escape a jam
- The ⇄ button switches between Challenge and Zen mode
技巧
- If a new item lands next to another of the same tier it auto-cascades — combos multiply the score
- Always keep empty cells: every merge spawns new items
- The rainbow ★ item is a wildcard — it merges with any tier
- Complete missions to earn extra erase charges
