What You're Up Against
Level 640 paints Cat with 198 tiles across 4 colors, split into 8 cubes in the tray. You have 5 waiting slots and two nest holes.
- Blue: 130 tiles → cubes of 44, 37, 29, 20
- Green: 48 tiles → cubes of 38, 10
- Dark: 16 tiles → cubes of 16
- Violet: 4 tiles → cubes of 4
⚠️ 1 hidden “?” cube in the tray.
Spoiler: what they hide
Violet 4
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 Blue 29 cube.
- Send the Blue 20 cube.
- Send the Green 10 cube.
- Send the Blue 37 cube. Only ~31 of its 37 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 38 cube. Only ~25 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 Blue 44 cube. Only ~18 of its 44 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Violet 4 cube.
- Send the Dark 16 cube. Only ~12 of its 16 tiles are open at this point — 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.
