- Forest: 231 tiles → cubes of 49, 48, 44, 38, 30, 22
- Aqua: 147 tiles → cubes of 55, 49, 23, 20
- White: 87 tiles → cubes of 51, 36
- Black: 14 tiles → cubes of 14
- Green: 5 tiles → cubes of 5
⚠️ 2 hidden “?” cubes in the tray.
Spoiler: what they hide
Aqua 49, Aqua 23
🔒 1 locked cube — free the cube above them before they can be picked.
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 Aqua 23 cube.
- Send the Forest 22 cube.
- Send the Aqua 20 cube.
- Send the Aqua 55 cube. Only ~33 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 Forest 44 cube. Only ~29 of its 44 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Forest 30 cube.
- Send the Forest 38 cube. Only ~26 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 Aqua 49 cube. Only ~24 of its 49 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the White 51 cube. Only ~16 of its 51 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Green 5 cube.
- Send the Forest 49 cube. Only ~20 of its 49 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Forest 48 cube. Only ~19 of its 48 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 14 cube.
- Send the White 36 cube. Only ~21 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.
Finish without boosters for 3 stars and bonus coins. If the board jams anyway, a Shuffle or Vacuum booster is the cheapest way out.
