Ghost Sort

About this game

A Halloween water-sort puzzle. Tap potion flasks to pour ghostly liquids and sort every color — but every 6 pours, the ghosts drift and two flasks swap places.

How to play

1. Tap a flask to lift it, then tap a second flask to pour the top layer of ghostly liquid across.
2. You can only pour onto the same color or into an empty flask, and only if there is room — each flask holds 4 layers, and only the top run of matching color moves.
3. The ghost drift: every 6 pours, two unfinished flasks swap places through a ghostly portal. A banner warns you one pour before it happens.
4. Sort every color into its own flask to clear the level. Undo is free, and restart resets the level.

Tips

• Finish at or under par to earn 3 stars — plan the pour order before you start moving liquid.
• When the drift warning appears, avoid setting up a pour the swap is about to undo.
• Keep one flask empty as long as you can: it's your buffer for unmixing a bad stack.
