How the game works
You pour liquid pigment between test tubes to sort it. Tap a tube to pick it up, then tap a second tube to pour into it; tapping the lifted tube again puts it down. There is no dragging.
A pour is allowed into an empty tube, onto the same colour, or onto a colour it can blend with — and only if there is room. Anything else is simply refused, so you cannot make an illegal move by accident.
Blending, and why it cannot be undone
Red, yellow and blue are what a level deals you. Orange, green and purple can only be made:
- red + yellow = orange
- yellow + blue = green
- red + blue = purple
A blended colour never blends again. That is the heart of the game: the moment you make an orange, that tube is committed.
“I sorted every tube but did not win”
The goal is the order along the top of the screen, which names how many tubes of each colour the level wants — two blue, one orange, one purple. One colour per tube is not a win on its own; the counts have to match the order exactly.
“The level says it can no longer be won”
You have made more tubes of a colour than the order asked for, and because a blend is permanent there is no way back. Use Undo, or restart the level from the pause button. Restarting is always free — no purchase is ever needed to recover a board.
Hints, Undo and Reveal
Hint suggests the next pour and tells you what it is for (“this finishes a tube”, “you need green — this board cannot be finished without it”). Undo takes back your last pour. Reveal makes the suggested pour for you. All three are earned by playing, and are free while VIP Club is active.
Progress, stars and the endless tail
There are 240 handcrafted levels, then an endless run of generated ones. Every board is seeded from its level number, so level 88 is the same board on every device. Stars reward a short, quick solve — but finishing a level is always worth at least one star, and there is no countdown and no move limit.
Purchases & restoring
VIP Club is an auto-renewable weekly subscription with a 3-day free trial; manage or cancel it in your App Store or Google Play account settings. Use Restore Purchases in Settings if a purchase does not appear on a new device. Refunds are handled by Apple or Google under their own policies. See the Terms of Use for the full detail.
Lost progress
Progress is stored on your device, so uninstalling the Game removes it. Your leaderboard entry is kept against an anonymous ID — contact us with your display name if you need it moved or deleted.
