About this game

Chroma Chain is a calm block puzzle with a twist you will not find anywhere else: colour chains.

Drag blocks onto an 8×8 board. Full rows and columns clear — that part you know. Here is the difference: every block has a colour. When half a cleared line shares one colour, a chain reaction fires and takes every connected cell of that colour with it. One line becomes twenty cells. Twenty cells become your new best score.

Fill lines and you will do fine. Group colours and you will go far.

WHAT IS INSIDE

• No timer, no countdown, no rush — you set the pace
• Colour chains as a second layer of thinking on top of the classic block puzzle
• Perfect Chroma: a line in a single colour, the rare big one
• Combo multiplier up to ×4 for clearing on consecutive moves
• Daily board: the same board for everyone, every day
• Hammer, shuffle and undo for when it gets tight
• Six colour sets to unlock
• Achievements and daily goals
• Five languages: English, German, Spanish, French, Italian

BUILT TO BE ACCESSIBLE

Turn on symbols and every colour is also readable by its shape. Motion can be reduced. Every dialog works with a keyboard and a screen reader.

HONEST ABOUT ADS

The banner sits right at the bottom, below the buttons — it never takes a cell away from the board. Videos only run when you start them yourself: for coins, for boosters, or to keep playing after a game over. Between runs there is an occasional ad, spaced out and capped.

No account, no sign-up, no pressure. Just open it and play.
Place blocks, clear lines, trigger colour chains. No timer, no time pressure.
