Spoiler: what they hide
Violet 24, Violet 12
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 Violet 12 cube.
- Send the Cyan 4 cube.
- Send the Yellow 43 cube. Only ~23 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 Yellow 47 cube. Only ~18 of its 47 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 19 cube.
- Send the Cyan 23 cube. Only ~20 of its 23 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 24 cube.
- Send the Dark 54 cube. Only ~34 of its 54 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 55 cube. Only ~25 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 Violet 24 cube. Only ~18 of its 24 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 38 cube. Only ~24 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 Teal 12 cube. Only ~10 of its 12 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.
