How do I merge nukes in Merge a Nuke?
Drag two nukes of the same merge level together — only identical tiers combine (2+2=4, 4+4=8). High-tier nukes cannot merge with lower bombs.

Core mechanic
How to Merge Nukes
Merging is the heart of Merge a Nuke. Drag identical tiers together, double the level each time, and climb toward stronger passive income and raid damage.
Same level only
You can only merge two nukes of the exact same tier — a 4 with a 4, an 8 with an 8, and so on.
Doubles each step
Two level-2 nukes become level 4. Two level-4s become level 8. The merge number doubles every time.
No mixing high and low
A high-tier nuke cannot merge with a lower-tier bomb. Drag duplicates together or leave them apart.
Clear board space first
A full base slows every decision. Merge the lowest duplicates first to open tiles for new spawns.
Step-by-step merge flow
- Step 1
Spawn or buy bombs
New nukes appear on your island automatically after Store upgrades, or from code rewards.
- Step 2
Find matching pairs
Look for two nukes with the same level number or identical appearance.
- Step 3
Drag one onto the other
On PC, drag and drop. On mobile, tap and drag. They combine into the next tier up.
- Step 4
Chain upward
Keep merging duplicates toward 16, 32, 64, and beyond. Higher tiers earn more cash per second.
- Step 5
Lock if threatened
If another player is raiding, activate Lock Base before you lose your merge chain.
Common mistakes
- — Hoarding many low-tier bombs instead of merging them immediately.
- — Letting the board fill up so new spawns have nowhere to land.
- — Trying to combine different tier levels and wondering why nothing happens.
- — Merging without locking first while other players are actively raiding.
Faster spawns come from Store upgrades. See which nuke names to chase on the Tier List.
Common beginner questions
Short answers for this guide. For the full wiki FAQ, visit all questions.
What should beginners buy first in the Store?
Redeem codes first, then buy Spawn Speed, then Spawn Tier so new nukes spawn at higher levels. See the full upgrade order on the Upgrades guide.
When should a new player start raiding?
Wait until your income is stable and you can lock your base. Raiding too early can stall growth if you lose merge progress.
How do I protect my base as a beginner?
Activate Lock Base before merging in busy lobbies and always lock before logging off. Keep your layout tidy so merges stay fast.
