What You're Up Against
Level 40 paints Fish with 120 tiles across 4 colors, split into 6 cubes in the tray. You have 5 waiting slots and two nest holes.
- Green: 70 tiles → cubes of 29, 21, 20
- Pink: 38 tiles → cubes of 38
- Lime: 6 tiles → cubes of 6
- Jade: 6 tiles → cubes of 6
⚠️ 1 hidden “?” cube in the tray.
Spoiler: what they hide
Jade 6
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 Green 20 cube. Only ~19 of its 20 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Pink 38 cube. Only ~18 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 Green 21 cube.
- Send the Green 29 cube. Only ~16 of its 29 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Lime 6 cube.
- Send the Jade 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.
