What You're Up Against
Level 31 paints Sun with 324 tiles across 4 colors, split into 18 cubes in the tray. You have 5 waiting slots and two nest holes.
- Forest: 216 tiles → cubes of 28, 26, 25, 25, 24, 23, 22, 19, 17, 7
- Green: 56 tiles → cubes of 22, 19, 11, 4
- Sand: 46 tiles → cubes of 22, 15, 9
- Purple: 6 tiles → cubes of 6
⚠️ 1 hidden “?” cube in the tray.
Spoiler: what they hide
Purple 6
🔒 1 locked cube — free the cube above them before they can be picked.
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 Forest 26 cube.

- Send the Forest 17 cube.
- Send the Sand 15 cube.
- Send the Sand 9 cube.
- Send the Forest 7 cube.
- Send the Green 4 cube.
- Send the Sand 22 cube. Only ~11 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 Purple 6 cube.
Finish without boosters for 3 stars and bonus coins. If the board jams anyway, a Shuffle or Vacuum booster is the cheapest way out.
