What You're Up Against
Level 637 paints Tree with 173 tiles across 4 colors, split into 7 cubes in the tray. You have 5 waiting slots and two nest holes.
- Brown: 115 tiles → cubes of 38, 27, 26, 24
- White: 26 tiles → cubes of 26
- Purple: 22 tiles → cubes of 22
- Forest: 10 tiles → cubes of 10
⚠️ 1 hidden “?” cube in the tray.
Spoiler: what they hide
White 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 “?” 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 Brown 27 cube.
- Send the Brown 26 cube.
- Send the Brown 24 cube.
- Send the White 26 cube. Only ~22 of its 26 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Brown 38 cube. Only ~15 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 Purple 22 cube. Only ~17 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 Forest 10 cube. Only ~9 of its 10 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.
