What You're Up Against

Level 307 paints Tree with 173 tiles across 4 colors, split into 7 cubes in the tray. You have 5 waiting slots and two nest holes.

  • Purple: 115 tiles โ†’ cubes of 48, 27, 24, 16
  • Coral: 26 tiles โ†’ cubes of 26
  • Brown: 22 tiles โ†’ cubes of 22
  • Aqua: 10 tiles โ†’ cubes of 10

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

Spoiler: what they hide

Coral 26

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 Purple 27 cube.
  2. Send the Purple 24 cube.
  3. Send the Purple 16 cube.
  4. Send the Coral 26 cube. Only ~22 of its 26 tiles are open at this point โ€” park it in a slot and let the surrounding colors clear the rest of the way.
  5. Send the Purple 48 cube. Only ~20 of its 48 tiles are open at this point โ€” park it in a slot and let the surrounding colors clear the rest of the way.
  6. Send the Brown 22 cube. Only ~17 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.
  7. Send the Aqua 10 cube. Only ~9 of its 10 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.
