How to play
Make similar coloured matches where four blocks meet. Make matches with locked blocks to unlock them. Match the target colour to fully recharge the timer, or match any other colour to partially recharge. When the timer runs out some blocks will be locked. Make multiple matches on a single block to get a bonus on that blocks next match. When fully charged, the Shuffle button allows you to change the game board if you get stuck with no possible matches.
