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 Jade 6 cube.
- Send the Purple 5 cube.
- Send the Navy 34 cube. Only ~16 of its 34 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Purple 21 cube. Only ~20 of its 21 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Purple 26 cube. Only ~17 of its 26 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Jade 22 cube. Only ~13 of its 22 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Cyan 18 cube. Only ~10 of its 18 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Red 9 cube. Only ~8 of its 9 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.
