What You're Up Against
Level 503 paints Mushroom with 170 tiles across 4 colors, split into 8 cubes in the tray. You have 5 waiting slots and two nest holes.
- Coral: 76 tiles → cubes of 25, 21, 19, 11
- Navy: 38 tiles → cubes of 38
- White: 32 tiles → cubes of 24, 8
- Blue: 24 tiles → cubes of 24
⚠️ 1 hidden “?” cube in the tray.
Spoiler: what they hide
White 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 Coral 25 cube.
- Send the Coral 21 cube.
- Send the Coral 11 cube.
- Send the White 8 cube.
- Send the White 24 cube. Only ~22 of its 24 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Navy 38 cube. Only ~13 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 Coral 19 cube. Only ~15 of its 19 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 24 cube. Only ~18 of its 24 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.
