What You're Up Against

Level 42 paints House with 223 tiles across 5 colors, split into 11 cubes in the tray. You have 5 waiting slots and two nest holes.

  • Indigo: 81 tiles โ†’ cubes of 37, 25, 15, 4
  • Brown: 54 tiles โ†’ cubes of 39, 15
  • Dark: 50 tiles โ†’ cubes of 30, 20
  • Forest: 20 tiles โ†’ cubes of 16, 4
  • Green: 18 tiles โ†’ cubes of 18

โš ๏ธ 1 hidden โ€œ?โ€ cube in the tray.

Spoiler: what they hide

Brown 15

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€œ?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.

  1. Send the Dark 20 cube.
  2. Send the Brown 15 cube.
  3. Send the Indigo 15 cube.
  4. Send the Indigo 4 cube.
  5. Send the Forest 4 cube.
  6. Send the Brown 39 cube. Only ~33 of its 39 tiles are open at this point โ€” park it in a slot and let the surrounding colors clear the rest of the way.
  7. Send the Indigo 25 cube. Only ~18 of its 25 tiles are open at this point โ€” park it in a slot and let the surrounding colors clear the rest of the way.
  8. Send the Dark 30 cube. Only ~16 of its 30 tiles are open at this point โ€” park it in a slot and let the surrounding colors clear the rest of the way.
  9. Send the Indigo 37 cube. Only ~23 of its 37 tiles are open at this point โ€” park it in a slot and let the surrounding colors clear the rest of the way.
  10. Send the Green 18 cube. Only ~14 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.
  11. Send the Forest 16 cube. Only ~12 of its 16 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.
