Game Components

  • 75 Chromino tiles, all unique, using combinations of 5 colours;
    • 🟥 🟨 🟩 🟦 🟪
  • 5 Chameleon Chromino tiles, combining 2 different colours and a central square with a Chameleon symbol;
  • 1 bag containing all the Chromino tiles and used to draw from;

Principle and aim of the game

The principle of the game is to play your Chromino tiles next to each other with at least two contacts between identically coloured squares.

Note if there are additional contacts made, those extra contacts *cannot* be of different colours. That is, each contact must be a pairing of colours.

As well as the 75 basic tiles, there are also 5 Chameleon Chromino tiles. Their central square with Chameleon symbol is surrounded by 2 normal coloured squares. The central square of a Chameleon Chromino can be placed in contact with any other colour. This means it can therefore be in contact with one colour on one side and a different colour on the other!

Each player attempts to be the first to play all the Chromino tiles dealt at the beginning or drawn during the game.

The winner is the first player to play all their Chromino tiles.

Setting up the game

  1. Before the game begins, the players should look for a Chameleon Chromino tile. This first tile should be placed colour-side-up in the center of the table. This Chromino tile will be the base around which the game will be built.
  2. All the remaining Chromino tiles are placed in the bag.
  3. Next, each player in turn draws eight tiles from the bag at random and places them on the table in front of themselves without showing the tiles to the other players.

The game can then begin.

Playing the game

The first player is randomly picked and the game is then played in sequence, one player after the other.

When it is a player’s turn to play, two situations can occur:

  1. The player has a Chromino tile they can place on the table according to the minimum two contacts rule. They play their Chromino, and the turn passes to the next player.
  2. The player cannot place any of their Chromino tiles: they must draw another Chromino randomly from the bag (if there are any left).
    • If they can, the player may place the drawn Chromino tile. The turn passes on to the next player.
    • If they can’t place the Chromino tile, the player must keep it and pass their turn. The turn passes on to the next player.

It should be mentioned that the more the game spreads, the more possibilities you will have for fulfilling the two contact rule. It is, in fact, often possible to be able to make 3, 4, 5 or even 6 contacts when placing a single Chromino tile.

Chromino colour matches

Ending the game

As soon as a player is left with only one remaining Chromino, they should place it colour side up in front of them, so it is visible to all.

A player cannot play a Chameleon Chameleon Chromino as their last tile. If the last tile they have left is a Chameleon Chromino they will have to draw a new tile.

The first player to place their last Chromino tile wins the game. However, the other players should continue to play until the end of the current turn, and if any other players managed to place their last Chromino during this last turn, they will be declared joint winners.

Game Options

Player Assistance

Different levels of player assistance are available to help you play Chromino with the least friction.


  • Playable tiles are highlighted
  • Where they can be placed is highlighted
  • You will be unable to draw a new tile if the player assistance can see that you have a valid move available
  • In Expert Play, you can see how many points you will earn for each tile BEFORE you make the move.


In this mode all the Player Assistance from the Beginner level is present, minus the restriction on Tile Drawing. You are able to draw a tile, even if there is a valid move available. Use this to your advantage buy building a good hand for quick finishes or high-scoring combos.


No assistance is given. Only for master players 😎

Alternative Rulesets

Junior Play

If you are playing Chromino with young children, you can teach them to play by playing the game like regular Dominoes, by only making a single contact of identical colour between the ends of the tiles.

By placing the Chameleon Chromino tiles perpendicularly (like doubles in the gameof Dominoes), the game will be able to spread in several directions, as this is one of the specificities of Chromino.

Expert Play

It is possible, and even recommended for regular players, to play Chromino by giving a score to each tile placement, depending on the complexity of the tile itself and the position it is finally placed in.

  1. Each Chromino is given a value equal to the number of different colours it is made up of (1, 2 or 3 points - Chameleon Chameleon Chromino tiles being worth 3 points).
  2. As each Chromino tile is placed, add the value of the Chromino being placed to the value of all the tiles it is placed in contact with.


A no stress mode, to see how quickly you can clear your hand. A great way to both practice recognising patterns and training for your finishing plays.
