Escape Tsunami for Brainrots on Roblox uses three distinct currency systems, and each one unlocks different rewards. Standard money fuels your speed upgrades and Brainrot slots. Radioactive Coins power a limited-time spin wheel. Trade Tokens let you buy Divine-rarity items from the Mystery Merchant. Knowing how each currency works — and when it becomes available — is the difference between grinding aimlessly and progressing fast.
Quick answer: Standard money comes from placing and upgrading Brainrots at your base. Radioactive Coins drop only during hourly Radioactive Events (hit bombs, run Toxic Waste Tunnels). Trade Tokens require collecting Yellow Trade Tickets during the Arcade Event and exchanging them at the Arcade Machine in the Legendary Area.
How standard money works
Money is the primary currency in Escape Tsunami for Brainrots. You spend it on speed upgrades, Brainrot slot expansions, and Brainrot level-ups. Every Brainrot you place on your base generates money per second, and the amount scales with rarity, mutation type, and upgrade level. A freshly placed unit might earn millions per second, but a fully upgraded Secret or Celestial Brainrot can push into the hundreds of billions.
Because the rebirth system is gated by speed rather than cash, efficient players often accumulate more money than they need. The trick is directing that surplus into the right upgrades at the right time.
Fastest ways to earn money early
Skip the common and uncommon Brainrots at the start. Instead, like the game on its official Roblox page to unlock two free Epic Brainrots — Sigma Boy, found directly in front of your base, and Guesto Angelico, located beside the Carry Upgrades shop. These generate far more income than anything you'll pick up on the runway in the first few minutes.
Once you have a baseline income, pour money into speed upgrades until you hit roughly 140 speed. That threshold lets you safely cross the Cosmic Area wall and reach the Secret and Celestial zones, where the highest-value Brainrots spawn. Only attempt runs during slow or super-slow tsunami waves, and remember that every Brainrot you pick up has a despawn timer — get back to base before it expires.
Scaling money with mutations, upgrades, and rebirths
Mutated Brainrots earn more than their normal counterparts. Electric and Diamond mutations are particularly valuable for income. The best window to farm mutated units is during admin-hosted events, when spawn rates and rewards increase. Prioritize upgrading your highest-rarity mutated Brainrots first, since the income multiplier from levels compounds with the mutation bonus.
Rebirthing resets your speed stats but applies a permanent money multiplier to every Brainrot on your base. It's one of the strongest long-term income tools in the game. Build speed, rebirth, rebuild speed, and repeat — each cycle makes your base generate significantly more cash.
Two other upgrades matter for income scaling. Carry Upgrades let you bring multiple Brainrots back from a single runway run, so you're not wasting high-speed trips on a single pickup. Brainrot slot expansions increase the total number of units your base can hold. Start investing in extra slots once you have four or five Secret-tier Brainrots or higher.
How to get Radioactive Coins
Radioactive Coins are an event-only currency. Radioactive Events trigger once per hour and last about five minutes. The in-game notice board displays a countdown to the next one, so keep an eye on it between tsunami waves.
During the event, two activities award Radioactive Coins:
Radioactive Bombs — Bombardino Crocodilos spawn across the map and drop glowing bombs. Hit the bombs with your bat repeatedly until they explode, showering the area with coins. Collect as many as you can before the event timer runs out.
Toxic Waste Tunnels — These appear off to the side of the safe pit area. Enter a tunnel and complete the parkour course inside. Finishing it awards 30 Radioactive Coins or, occasionally, a Radioactive Lucky Block.
Radioactive Spin rewards
Radioactive Coins feed into the Radioactive Spin, which costs 20 coins per spin. The reward pool and approximate drop rates break down like this:
| Reward | Drop chance |
|---|---|
| Radioactive Random Cosmic | 53.2% |
| Radioactive Random Secret | 29.6% |
| 2× Server Luck | 11.8% |
| Radioactive Random Celestial | 5.3% |
| Radioactive Lucky Block | 0.1% |
| Radioactive Bulbito Bandito Traktorrito | 0.001% |
These rewards are exclusive to the Radioactive Spin — there's no other way to obtain them. Stockpiling coins across multiple events before spending them all at once is a solid approach if you want to maximize your chances at the rarer drops.
How to get Trade Tokens
Trade Tokens are the rarest free currency. They're used at the Mystery Merchant to purchase Divine-rarity items, including the Arcade Lucky Block, the Glitch Base Skin, and a VIP Gamepass. There are four ways to earn them.
Arcade Event — The best free method
The Arcade Event spawns randomly once per hour and lasts around 10 minutes. While it's active, Yellow Trade Tickets appear scattered across the map. Collect as many as possible before the timer expires.
Step 1: When the Arcade Event notification appears, run across the map and pick up Yellow Trade Tickets. They look distinct from other collectibles, so they're easy to spot.
Step 2: Head to the Legendary Area of the map. On the left side of the safe pit, you'll find a hole that leads into a hidden arcade-themed room containing the Arcade Machine.
Step 3: Interact with the Arcade Machine. You need a minimum of three Yellow Trade Tickets to make an exchange. Every three tickets convert into a set number of Trade Tokens.
The event window is short, so prioritize ticket collection over everything else while it's running. Speed upgrades help you cover more ground.
Admin Abuse Events
Admin-hosted sessions like Wave Wednesdays can also drop Trade Tokens. These events work differently from the Arcade Event — you don't need to collect tickets. Just play the game normally during the admin session. Because the admin hosts the server directly, reward rates are boosted, which increases the chance of receiving Trade Tokens as part of your regular gameplay loop.
Admin events aren't on a fixed hourly schedule, so they're less predictable than the Arcade Event. Check community channels for announcements about when the next one is happening.
Buying Trade Tokens with Robux
If you're willing to spend Robux, you can purchase Trade Tokens directly through the in-game shop or the Mystery Merchant shop in the lobby. The tokens arrive instantly and can be spent immediately on Divine-rarity Lucky Blocks, Base Skins, and other premium items. For free-to-play players, the Arcade Event and Admin Abuse sessions remain the primary paths.
Trading with other players
You can also acquire Trade Tokens by trading high-value Brainrots or Base Skins with other players on the same server. Open the Trade Menu on the left side of the screen, select a player, add your items to the trade window, and request Trade Tokens in return.
The risk here is real. You'll typically need to offer Divine-rarity or exclusive Brainrots to get a meaningful number of tokens, and the exchange rate depends entirely on what the other player is willing to accept. Always weigh whether the tokens you'd receive are enough to buy something worthwhile from the Mystery Merchant before confirming the trade.
Escape Tsunami for Brainrots layers its currencies deliberately — standard money keeps you progressing, Radioactive Coins gate exclusive mutated units, and Trade Tokens unlock the game's most powerful Divine items. Staying aware of event timers and spending your coins strategically will get you further than any single grinding session.
