Spoiler: what they hide
Cyan 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 โ?โ 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 Cyan 20 cube.
- Send the Cyan 52 cube. Only ~27 of its 52 tiles are open at this point โ park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Green 24 cube.
- Send the Green 46 cube. Only ~22 of its 46 tiles are open at this point โ park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Purple 22 cube. Only ~14 of its 22 tiles are open at this point โ park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Cream 18 cube. Only ~16 of its 18 tiles are open at this point โ 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.
