☢️ Nuke Your City FAQ

Nuke Your City is a Roblox idle simulator by Nuclear Fun, launched March 16, 2026. Players grow explosives via a Dropper machine, load them into a rocket, and launch nukes at a city for cash — which is reinvested into upgrades to produce bigger and bigger explosions.

Yes. Nuke Your City is completely free to play on Roblox across PC, Mac, iOS, Android, and Xbox. No purchase is required to access any core game mechanic.

Wait for your Explosive to fill to 100 EXP via the Dropper. Then interact with the Rocket to load your Explosive. Once loaded, press the Control button to fire the nuke and receive your cash reward.

The Control button triggers the nuke launch once your Explosive is loaded into the Rocket. It is the final step of the gameplay loop before cash is awarded based on your EXP level.

Nuke Your City was developed by Nuclear Fun, a Roblox developer active on X (Twitter) as @jett_str. The game launched on March 16, 2026 and quickly became one of Roblox's fastest-growing simulators.

The confirmed working code is BOOM (all caps). Redeem it via the ABX icon in the top-right of the screen in-game. It rewards 50–100 Playtime Points and 1 free Crate.

Click the ABX icon in the top-right corner of your screen while in the game, or scroll to the bottom of the Shop menu to find the code input box. Type the code and press Redeem.

The most common reasons are: the code has already been redeemed on your account (each code is one-time per account), the code is case-sensitive and must be entered in ALL CAPS, or the code has expired.

New codes are announced first on the official Discord (discord.com/invite/A2mQCuFTbz), then on the developer's X account @jett_str, then on NukeYourCity.Wiki. Follow Discord announcements for the fastest code alerts.

Playtime Points accumulate over time and through codes like BOOM. They contribute to advancing your Research tree — unlocking permanent Research Upgrades that carry over across all Rebirths forever.

Research Points are earned primarily through the Rebirth mechanic — resetting your run at a progression milestone awards Research Points based on how far you got. Playtime Points (earned passively and via codes) also contribute to Research tree advancement.

Rebirth is the game's prestige mechanic. You reset your Machines and cash in exchange for Research Points, which unlock permanent Research Upgrades. These upgrades make all future runs progressively faster. It's the core long-term progression system.

Rebirth when your Research Point gain would let you return to your current progress point in under 50% of the original time. For most players, this occurs after 2–4 hours of active play on the first run.

Yes. Your Dropper continues filling your Explosive with EXP even when you're completely logged out. This is server-side and requires no app activity. Offline progress is one of the game's core mechanics — listed explicitly in the official game description.

Dropper Level 2, then 3, 4, and 5 — buying all five levels before any Machine purchase. The Dropper is the foundation of all EXP generation and has the best ROI in early game.

The Dropper generates raw EXP over time. Machines are passive multipliers that increase the value of your EXP or your explosion cash output. Think Dropper = engine speed, Machines = turbocharger multipliers.

Yes. All Machines and Dropper levels reset to zero on Rebirth. Only Research Upgrades (unlocked with Research Points) and redeemed codes persist across Rebirths permanently.

Max Dropper to level 5 → buy Blast Amplifier → buy Offline Collector → continue Dropper to level 10 → Rebirth at the correct timing threshold → unlock Passive EXP Boost and Offline Efficiency Research immediately. This sequence minimizes time-to-max-nuke.

Passive EXP Boost Rank 1 immediately after your first Rebirth, then Offline Efficiency Rank 1. These two compound across every single future run and provide the largest total long-term speed increase in the game.

Always wait for higher EXP. EXP scaling is exponential — a launch at 200 EXP produces vastly more cash than two launches at 100 EXP. More cash per launch = faster upgrade purchases = faster progression.

The Offline Collector Machine (A-Tier) is the best investment for idle players. It multiplies your offline EXP generation rate by approximately 3x from the moment you purchase it. Pair with Offline Efficiency Research after your first Rebirth for 6x total offline rate.

No third-party script is safe. All scripts require a Roblox executor, which violates the Roblox Terms of Service and is detected by the Byfron/Hyperion anti-cheat. The consequence is a permanent account ban. The game's built-in offline mechanics already replicate every feature these scripts claim to offer.

Yes. Using an external executor to run any script — including autofarming scripts — violates Roblox ToS and triggers Byfron anti-cheat detection, resulting in a permanent account ban.

Top 5 players on a server have launched the highest EXP nukes. At that level, the explosion covers virtually the entire city map with a towering mushroom cloud effect. Players typically need 3–5 Rebirths and all S/A-tier Machines to reach this tier.

Community shorthand for a nuke launched at approximately 3x the base EXP threshold. These informal numbers (2 nuke, 3 nuke, 5 nuke, 8 nuke) represent relative power milestones based on observed visual explosion differences at certain EXP levels.

Max nuke power depends on your Machine upgrades and Research tier. With fully upgraded Machines and multiple Rebirths, players reach the highest explosion scale. The ceiling scales with your progression — there is no fixed hard cap.
