Klax (New)

Very tidy conversion of the Atari classic, but not quite as slick as the Lynx version. Thankfully not as rare as Tengen's Mega Drive releases. Coloured blocks must be matched in connect four style as they trundle along towards you. Every dropped block costs a life. Doesn't sound much, but like any good puzzle game easy to pick up and compelling enough not to want to put down.
