Each turn of a player either consists of

• Turning a card. The card then shows one of his pieces. The player places the piece on an empty square on the board. A few rules determine where the piece can be placed: pawns cannot be placed at the first or one of the two last rows (seen from the players side), and kings cannot be placed in check.
• Making a regular chess move. This is only allowed when the king has been placed. The usual chess rules apply. When a pawn promotes, one of the four promotion pieces is used; a player can thus promote at most four pawns.

The website of Rainbowchess has information in several languages, including English, French, German, Danish, and Czech. The website contains information on events (like presentation meetings, e.g. at Dutch schools, tournaments), an online shop where you can buy sets of the game, an online program where you can play the game against yourself. The online shop offers two types of sets: Standard and basic, for prices (end 2011) around 35 and 24 euro's. The standard set is a complete game; the basic set excludes one set of standard chess pieces. In the latter case, one can then just add these from a standard set game. Also, packs of four sets are sold with a discount (school and club set).
