If you are interested in filler games, or portable boardgames to bring along on travel trips, then the Rainbow Deck is for you! It is basically a 100-games-in-1 cardgame system.

The Rainbow Deck (RD) is a cardgame system that has a total of 162 cards. There are 12 suits with each suit having 13 ranks, and 6 Joker cards. The suits are represented by both colour and number. The ranks are from 0 to 9, J to K. The cards also numbered from 0 to 119, and have letters from A to Z.

The RD can be adapted to play a variety of games, just like a deck of Poker cards. The difference is that the RD has 8 more suits, numbers from 0 to 119 as well as alphabet letters, thus it is most suitable for playing abstract games that require numbers, colours or letters. It can also be used by game designers as components in their own prototype games. Players can also combine the RD with other boardgames with components having colours, numbers or letters to form new games!

The RD can be complemented by 6 colours x 27 chips and 6 coloured dice. This allows playing of cardgames that require chips or dice. Also, the cardbacks have a 2x3 checkerboard pattern and they can be used to form boards which, together with the chips, can be used to play a variety of abstract games.

Decks that the RD can be mapped into
- Sequence of numbers of 0 to 119
- Letters with values similar to Letter Head
- 12 suits (colour/number) x 1-13 values
- 6 suits (icon) x 1-23 values (2x10+3)
