What You're Up Against
Level 840 paints Gift with 236 tiles across 4 colors, split into 9 cubes in the tray. You have 5 waiting slots and two nest holes.
- Sand: 130 tiles → cubes of 42, 38, 20, 19, 11
- Jade: 42 tiles → cubes of 42
- Red: 38 tiles → cubes of 38
- Orange: 26 tiles → cubes of 20, 6
⚠️ 1 hidden “?” cube in the tray.
Spoiler: what they hide
Sand 11
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 Sand 20 cube.
- Send the Sand 19 cube.
- Send the Sand 11 cube.
- Send the Orange 6 cube.
- Send the Sand 38 cube. Only ~28 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 Jade 42 cube. Only ~24 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 Sand 42 cube. Only ~25 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 Red 38 cube. Only ~25 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 Orange 20 cube. Only ~16 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.
Finish without boosters for 3 stars and bonus coins. If the board jams anyway, a Shuffle or Vacuum booster is the cheapest way out.
