Battlejewels is simple to pick up — just match coloured mana gems together to clear them — and gives you a lot of meat to chew on as you play more. Delve into the game.. theres lots to fiddle with! There are dozens of gem-swapping games out there, but lets face it – you can play Bejewelled for hours on end, but why? Just to clear the level? Fine and good, they perfected the form. But in Battle Jewels you can clear the level, and smash the opponent too. Its as simple or as complex as you want .. play to clear, play to win, or play to level up.
