Quarta vs Chess Lab

Quarta is an original digital board game with a unique generative soundtrack, designed and created by Kennerspiel des Jahres nominated game designer Brett J. Gilbert and musician, software designer and Bloom co-creator Peter Chilvers. Two players take turns to place tiles, build areas of coloured ‘quarta’s, and claim those areas to control the three colours. Each game lasts only a few minutes, and is played until the tiles fill a 5×5 square. The winner is the player who controls the most colours at the end of the game. But Quarta is also something more. As you play, Quarta creates a totally unique piece of music – an individual soundtrack for every game – driven by the arrangement of areas built by the players. "Both challenging to the mind and relaxing at the same time, the perfect form of gaming." AppAdvice KEY FEATURES • Designed for digital: A brand new two-player tile game created especially for iOS. • Simple, engaging gameplay: Tutorial gets you playing in 60 seconds.
