Questions: Quick answers
1. Is the BOOM code still active? Yes. As of September 2026, BOOM in all capitals is the only confirmed active code. It redeems for Playtime Points (sources report 50 or 100) plus one Crate. There is no confirmed expired-codes list. See the Codes Hub and how to redeem.
2. What does BOOM give? Playtime Points and one Crate. Playtime Points feed the long-term research track. The Crate is a one-shot roll that may contain cash, explosives, or a timed boost. Open the Crate in a session you will play, not at logout. See code rewards.
3. How do I redeem codes? Two methods: the ABX icon in the top-right HUD, or the Shop scrolled to the bottom. Type BOOM in all capitals with no spaces. If it fails, check for a trailing space or a lowercase b. Full steps on how to redeem.
4. When should I rebirth? Rebirth when your nuclear dropper is already the only machine you bother feeding, and when the next cash spike would buy a money Research multiplier rather than another dropper level. Players commonly report about five Research Points per rebirth. The statue costs around 1.5 million cash early. See rebirth and upgrade priority.
5. What do I lose on rebirth? Machines, cash, fuse progress, and base layout. You keep Research Points and purchased Research upgrades. Totems and crates are account-bound and survive. Full wipe details on rebirth.
6. Is the nuclear dropper worth it? Yes, once plot expand is on the table. It is the S-tier late-game machine. Player reports place the early price around 85,000 cash after expand. It outpaces fountain, poison, and the starter pad once placed and upgraded. Full rankings on the machines tier list.
7. Does progress run while I am offline? Yes. Explosives keep filling from your droppers while you are logged out. Launches, codes, fuse waits, and rebirth do not run offline — those need a live session. See offline progress.
8. Can I play with friends? Servers hold up to six players. Bases are personal. The city is shared. VIP servers are not allowed, so you cannot reserve a private plot. Cross-play works across PC, Mac, iOS, Android, and Xbox on the same servers. See the players hub.
9. How do I get Research Points fast? Research Points come from rebirth (about five per wipe in player reports) and from Playtime Points accumulated through codes like BOOM. Money multipliers are the first Research purchase that shortens every future run. See rebirth and the research tier list.
10. What is the best machine order? Start: free manual dropper. After expand: nuclear dropper first, poison as the funded second. Fountain and fuse are support. Extra land only when the best producer is maxed. See the machines tier list and the upgrade priority planner.
11. Why does my nuke not launch? The explosive is under 100 EXP, or it is not loaded into the rocket. Steps: fill to 100 on the dropper, walk to the rocket, interact to load, then press Control. If Control never appears, the load step was skipped. See how to launch and controls.
12. Should I buy gamepasses? Auto Launch (29 Robux) is the only cheap row that matches a real pain. Double Cash and OP Dropper are late flex. Nothing replaces plot expand. See gamepasses.
13. Is this a single-player game? No. Servers are online and shared, up to six players. Personal bases are private; the city is public. Other players’ rockets can hit the same skyline you are aiming at. See idle vs active.
14. Where do new codes appear first? The official Discord and X @jett_str first. Then in-game. Then confirmed on this wiki. There is no weekly drop clock. See the Codes Hub.
15. How do totems and crates work? Totems are placeable multipliers that sit on your plot and boost cash after a launch. Crates are one-shot rolls from codes. The free group totem (3x money) is the cheapest S-tier item in the game. See the totems tier list.
