What is Merge a Nuke?
Merge a Nuke is a Roblox merge-and-raid idle game by Nuke The Game. The loop has three parts: you merge two identical bombs into one nuke a tier higher, your arsenal earns cash every second even while you are offline, and you can launch nukes at other players to steal their cash. Defence is a single button — locking your base — and forgetting it is the most common way new players lose progress.
It is playable on Desktop, Mobile, Tablet and Console, servers hold up to 8 players, and new content ships every Friday.
Step-by-Step Walkthrough
- 1
Learn the merge grid
Place identical bombs or nukes together and merge them into a higher tier. Higher tiers earn more cash per second.
Every merge doubles value — unmerged duplicates waste grid slots and income.Watch at 0:15 - 2
Prioritize income over raids
Your nukes generate cash continuously, even while offline. Focus on merging up before spending time raiding.
Passive income scales with merge depth — raids pay less until you reach the B band.Watch at 3:00 - 3
Lock before leaving
Always lock your base before closing the game. Unlocked bases can be raided and lose stored cash.
Locking is the last action before every break — see our Offline Earnings guide for the full logout checklist.Watch at 3:30 - 4
Redeem codes early
Free cash and nukes are pure merge fodder, so redeem before you grind. Clear plot space first — nuke rewards can be lost if you are at the spawn cap.

Raid when ready
Once you have a mid-band nuke and spare cash, launch your first raid on a weaker target to learn the mechanic. Hitting the same player three times declares war, so spread your hits if you only want a quick steal.
Controls
- PC: Mouse to select and move bombs; keyboard shortcuts per in-game prompts
- Mobile: Tap to select, drag to merge or move items on the grid
- Console: Gamepad navigation with on-screen merge and raid prompts
First Session Goals
In your first 30 minutes, aim to redeem every active code, merge up to at least the C band, and lock your base before your first break. Skip heavy raiding until passive income covers potential losses — see the Raid Guide when you are ready.
