Merge a Nuke Offline Earnings: 5 Tips to Maximize AFK Cash

Your nukes earn cash while you are offline in Merge a Nuke. Here is how to maximize AFK income and stop raiders from stealing it.

Jun 18, 2026

One of the best things about Merge a Nuke is that your nukes keep earning cash while you are offline. Set it up right and you log back in to a full bank. Set it up wrong and a raider empties it. Here is how to do it right.

1. Merge to your highest tier before logging off

Offline income is cash/sec × hours × 3600, and cash/sec is driven by your nuke tiers. Spend a minute merging duplicates up before you close the game — every tier you gain multiplies the whole offline session. Check the tier list for cash/sec by tier.

2. Fill your grid slots

Empty slots earn nothing. More high-tier nukes on the grid means more cash banked per second offline. Use Max Spawn upgrades to raise your slot count.

3. Lock your base — always

This is the one that catches everyone. An unlocked base can be raided while you sleep, wiping the cash your nukes earned. Make locking your base the last action before every logout. See the raid guide for how stealing works.

4. Equip a cash-multiplier commander

After the Commander Update, a cash-multiplier commander scales your offline income just like online income. It is the single best offline upgrade.

5. Estimate before you go

Use the offline cash calculator to project how much you will bank for a given number of hours. It is the fastest way to see whether chasing one more merge before bed is worth it.

Cash/sec values are community estimates and may shift after Friday balance patches — re-check the calculator and tier list after each update.
