What You're Up Against
Level 850 paints Rainbow with 388 tiles across 5 colors, split into 12 cubes in the tray. You have 5 waiting slots and two nest holes.
- Lime: 102 tiles → cubes of 37, 31, 19, 15
- Brown: 86 tiles → cubes of 55, 31
- Black: 74 tiles → cubes of 38, 36
- Blue: 66 tiles → cubes of 43, 23
- Coral: 60 tiles → cubes of 40, 20
⚠️ 2 hidden “?” cubes in the tray.
Spoiler: what they hide
Coral 40, Coral 20
Step-by-Step Solution
This loading order was computed from the web level layout with a reachability-first strategy: always feed the ants colors they can actually reach, and never let all 5 slots fill with blocked colors. Tap hidden “?” cubes only when you have slot room to absorb a surprise color.
Load the cubes in this order, letting the ants work between picks. Unless noted, a cube's tiles are fully reachable when you send it.
- Send the Blue 23 cube.
- Send the Coral 20 cube.
- Send the Lime 19 cube.
- Send the Lime 15 cube.
- Send the Blue 43 cube. Only ~26 of its 43 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Black 38 cube. Only ~30 of its 38 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Black 36 cube. Only ~23 of its 36 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Lime 31 cube. Only ~26 of its 31 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Lime 37 cube. Only ~20 of its 37 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Brown 31 cube.
- Send the Brown 55 cube. Only ~30 of its 55 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Coral 40 cube. Only ~34 of its 40 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
Finish without boosters for 3 stars and bonus coins. If the board jams anyway, a Shuffle or Vacuum booster is the cheapest way out.
