Colony Flow Boosters Guide: All 4 Power-Ups Explained
Colony Flow has four boosters. Each one unlocks at a specific level, can be bought with coins in the shop, and — this matters — using any booster caps the level at 2 stars. Finish clean for 3 stars, extra coins and a 55% chance of a free booster drop.
| Booster | Unlocks at | Shop price | Effect |
|---|---|---|---|
| ➕ Extra Slot | Level 3 | 🪙 40 | Adds one more waiting slot for the current level, up to a maximum of 7 (you start with 5). |
| 🔀 Shuffle | Level 4 | 🪙 40 | Rearranges the cubes left in the tray. Locked cubes keep their locked state but may end up in a different position — sometimes uncovered. |
| 🦾 Pick Up | Level 6 | 🪙 50 | Returns one cube from a waiting slot back to the tray (with its remaining count intact) and calls its ants home. Tap the booster, then tap the slot cube. |
| 🧹 Vacuum | Level 9 | 🪙 60 | Instantly clears every board tile of one color — plus all cubes of that color in the tray and slots. Tap the booster, then tap any visible cube of that color. |
➕ Extra Slot
Adds one more waiting slot for the current level, up to a maximum of 7 (you start with 5).
When to use it: Best used proactively on levels with many colors: two extra slots turn most jams into non-events. It's also the cheapest insurance when you're about to tap a hidden “?” cube.
🔀 Shuffle
Rearranges the cubes left in the tray. Locked cubes keep their locked state but may end up in a different position — sometimes uncovered.
When to use it: Use when the cube you need is locked underneath another cube you can't afford to pick up yet. A shuffle can free it without spending a slot.
🦾 Pick Up
Returns one cube from a waiting slot back to the tray (with its remaining count intact) and calls its ants home. Tap the booster, then tap the slot cube.
When to use it: The jam-breaker. If a slot is stuck holding a color the ants can't reach, send it back to the tray and load something reachable instead. Tap the booster again to cancel and get the charge refunded.
🧹 Vacuum
Instantly clears every board tile of one color — plus all cubes of that color in the tray and slots. Tap the booster, then tap any visible cube of that color.
When to use it: The nuke. Save it for late hard levels where one color is buried under everything else. It won't work on hidden “?” cubes — reveal them first.
Booster Economy Tips
- You start with 2 of each booster and 80 coins — enough for two shop purchases.
- Win rewards grow with level number (12 base coins, +1 per 5 levels up to +20, +8 for a no-booster clear).
- Pick Up and Vacuum can be canceled after activation by tapping the booster again — the charge is refunded.
- Never spend boosters on early levels; the written walkthroughs get you through levels 1–40 clean.
