Think you're good at puzzles? You've never experienced a fast action puzzler like this before! Crystal Clash competitively pits you against other online players around the world in realtime, requiring quick puzzle solving skills and fast reactions in order to win. In the world of Crystal Clash, you are the lord of your castle, and your soldiers, called "Bits", assist you in expanding your territory. Both you and your opponent simultaneously solve the same set of pixel logic puzzles, and with each correct fill, your Bits automatically advance and attack your opponent. Decide the best strategy for your Bits by controlling the lanes they attack on -- either keeping your defense strong, or pushing them all for a full attack to claim your opponent's area. For each puzzle you solve, you'll gain experience to level up your Bits, increasing their strength, defense, speed and hit points, and will unlock new and powerful skills for use in battle! Once you've powered up your Bits, enter the Rank Match where up to eight players all simultaneously battle to conquer and claim control over their expanding territory. Fight against the other Castle Lords, bringing peace to the land once again! Crystal Clash is continually being updated with additional features, with a new release approximately every two to three weeks.
