What You're Up Against
Level 638 paints Melon Pop with 191 tiles across 4 colors, split into 7 cubes in the tray. You have 5 waiting slots and two nest holes.
- Navy: 126 tiles → cubes of 49, 32, 25, 20
- Violet: 30 tiles → cubes of 30
- Dark: 20 tiles → cubes of 20
- Cyan: 15 tiles → cubes of 15
⚠️ 1 hidden “?” cube in the tray.
Spoiler: what they hide
Dark 20
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 Navy 25 cube.
- Send the Navy 20 cube.
- Send the Navy 49 cube. Only ~22 of its 49 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 30 cube. Only ~27 of its 30 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Navy 32 cube. Only ~17 of its 32 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Dark 20 cube. Only ~14 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 Cyan 15 cube. Only ~10 of its 15 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.
