What You're Up Against
Level 721 paints Umbrella with 140 tiles across 4 colors, split into 6 cubes in the tray. You have 5 waiting slots and two nest holes.
- Aqua: 71 tiles → cubes of 40, 31
- Red: 47 tiles → cubes of 30, 17
- Orange: 14 tiles → cubes of 14
- Brown: 8 tiles → cubes of 8
⚠️ 1 hidden “?” cube in the tray.
Spoiler: what they hide
Brown 8
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 Aqua 31 cube. Only ~30 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 Aqua 40 cube. Only ~18 of its 40 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Red 30 cube.
- Send the Red 17 cube.
- Send the Orange 14 cube.
- Send the Brown 8 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.
