Kvant Puzzle

Items keep coming and you have a handful of slots. Every move is the same question: put it down now, or keep the space for a full set?

Three identical items merge into one of a higher rank. The one that reaches the top of its chain leaves the board and frees up room. You win when the board is empty.

HOW IT PLAYS
• Tap an item, tap a slot — no dragging, one hand
• Three of a kind merge into one better item
• A completed chain leaves the board
• Out of space with no move left — level lost
• No need to rush: in STANDARD mode the belt stands still

WHAT IS INSIDE
• 99 levels laid out as a path across ten lands — from Snowbound Ridge and Ice Cavern, through Black Hollow, Old Mine, Haunted Graves, Jungle and Shore, on to the Desert, the Volcano Slopes and the Volcano Heart
• Two modes on the same levels: STANDARD, where the belt stands still, and ELITE, where it does not wait — though it slows down while you think
• PRO mode: ten timed levels, the same set for everyone in a given week, new every week
• Every tenth level is a ranked level that closes a land
• A world leaderboard through Play Games: once you sign in, your times from ranked levels go to a shared board, and the PRO run has one of its own
• A backpack for one item set aside, and a stock of undos for when a move turns out wrong
• Stats from your own runs: levels cleared, average time, share of merges

BUILT TO BE FAIR
Each of the 99 levels comes with a proof that it can be finished — a solver clears it before the level ships. The order of items is arranged, not random. When you lose, it is down to a decision, not to bad luck. The first four levels cost no lives.

SMALL THINGS THAT MATTER
• Portrait only, thumb-friendly
• No account, no sign-in
• Notifications are optional: one when your lives come back, and no daily nagging
• Ads are a choice, never a wall: when you run out of lives or undos, you can watch a short ad and keep playing
• Interface in Polish, English, German, French, Spanish and Portuguese

You can play without an account if you like — signing in to Play Games is needed only for the world leaderboard. The name on the local score board stays on your device.
