What You're Up Against
Level 221 paints Rainbow with 388 tiles across 5 colors, split into 15 cubes in the tray. You have 5 waiting slots and two nest holes.
- Dark: 102 tiles → cubes of 52, 27, 23
- Black: 86 tiles → cubes of 30, 28, 24, 4
- Pink: 74 tiles → cubes of 42, 32
- Red: 66 tiles → cubes of 25, 24, 17
- Orange: 60 tiles → cubes of 32, 22, 6
⚠️ 2 hidden “?” cubes in the tray.
Spoiler: what they hide
Orange 32, Orange 6
🔒 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 Red 25 cube.
- Send the Red 24 cube.
- Send the Red 17 cube.
- Send the Orange 6 cube.
- Send the Orange 22 cube.
- Send the Black 4 cube.
- Send the Pink 42 cube. Only ~30 of its 42 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 23 cube.
- Send the Dark 52 cube. Only ~25 of its 52 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Black 30 cube.
- Send the Black 24 cube.
- Send the Pink 32 cube. Only ~24 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 Orange 32 cube. Only ~21 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 Black 28 cube. Only ~24 of its 28 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 27 cube. Only ~20 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.
Finish without boosters for 3 stars and bonus coins. If the board jams anyway, a Shuffle or Vacuum booster is the cheapest way out.
