Frequently Asked Questions (FAQ)
Quick answers about merging rules, obstacles, coins, and local progress.
1. How do blocks merge and evolve?
When blocks of the same color and same level touch orthogonally (up, down, left, right) and reach the required threshold, they merge into the next level:
• Lv1 → Lv2: Requires 3 or more touching same-color Lv1 blocks.
• Lv2 → Lv3 → Lv4 → Lv5: Requires 2 or more touching same-color blocks of that level.
• Lv5 Star Blast: Merging 2 touching Lv5 blocks triggers a powerful blast that clears surrounding cells and awards bonus points!
2. How do I clear Ice, Stone, and Bomb obstacles?
• Ice Blocks: Frozen blocks have a color and level. Merge them with matching adjacent blocks or complete their row/column to shatter the ice.
• Stone Blocks: Stones cannot merge by color; clear them by filling their row or column, or blast them with a Lv5 merge.
• Countdown Bombs: Each piece placement reduces the bomb counter by 1. Trigger a merge in an orthogonally adjacent cell or clear the bomb's row/column before the timer hits 0 to defuse it!
3. How are 3-star ratings and coins awarded?
Complete the level goal (reaching a target block level or target score) before running out of moves. Your star rating (1 to 3 stars) is determined by the percentage of moves remaining when you win, rewarding you with in-game coins.
4. How does the 50-Coin Revive work?
If you run out of moves or a bomb detonates, you can spend 50 in-game coins (at most once per attempt) to continue the round. Coins are earned through normal gameplay; Version 1 has no in-app purchases.
5. Is my progress synced to the cloud if I switch devices or uninstall?
No. Version 1 keeps all progress, stars, coins, and settings 100% locally on your device with no user accounts or cloud servers. Uninstalling the app or clearing app data removes your local progress permanently.
6. How can I reduce visual effects or turn off sound/vibration?
Tap the Settings gear icon on the Home screen (or pause menu) to toggle Sound, Vibration, or Reduce Motion at any time.
