What You're Up Against
Level 51 paints Rainbow with 318 tiles across 5 colors, split into 14 cubes in the tray. You have 5 waiting slots and two nest holes.
- Coral: 80 tiles → cubes of 28, 26, 20, 6
- Yellow: 72 tiles → cubes of 31, 29, 12
- Violet: 62 tiles → cubes of 39, 16, 7
- Forest: 56 tiles → cubes of 29, 27
- Blue: 48 tiles → cubes of 31, 17
⚠️ 2 hidden “?” cubes in the tray.
Spoiler: what they hide
Blue 31, Blue 17
🔒 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 Blue 17 cube.
- Send the Violet 7 cube.
- Send the Coral 6 cube.
- Send the Forest 27 cube. Only ~24 of its 27 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 29 cube. Only ~20 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 Violet 16 cube.
- Send the Violet 39 cube. Only ~25 of its 39 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Coral 28 cube.
- Send the Coral 26 cube.
- Send the Yellow 12 cube.
- Send the Yellow 29 cube. Only ~23 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 Yellow 31 cube. Only ~26 of its 31 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 31 cube.
- Send the Coral 20 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.
