Start by merging duplicates into stronger nukes, collect cash before spending, redeem BOOM in the live client, lock before risky launches, and upgrade the system that slows the next merge or raid cycle.
The core loop is merge, earn, launch, and defend. Beginners should keep the board dense and cash moving before chasing raid chains.
Try BOOM in the live client, then use the reward only after the game shows what you received.
Launches are safest when your base defense is ready.
Merge matching low nukes immediately so the board keeps creating higher tiers instead of clogging with weak pieces. Learn the basic chain by combining equal nukes before focusing on raids.
Buy the upgrade that fixes the visible slowdown. If new nukes arrive too weak, push spawn tier; if the board runs out of room, push max spawn. Default spawn level and base capacity solve different problems.
Use the countdown to stack stronger nukes, collect cash, and avoid wasting space. Waiting passively leaves you with fewer launch options when the city opens.
Aim at parts of the city with buildings and rotate through ready nukes instead of clicking empty areas. Misses and low-building targets waste launches while the city health recovers.
Auto Merge is useful when manual combining becomes the main friction. It fits idle or low-attention sessions more than careful manual testing.
Keep the merge board moving, collect cash, and reach a stable lock-and-launch rhythm.
Yes, try BOOM in the in-game redeem menu, then read the reward message before planning around it.
Raid after your base lock is ready and your cash can be spent quickly.
Yes. Check returning cash before spending or changing your merge plan.
No. Use the live upgrade UI for exact costs and this guide for route decisions.
