A ridiculously simple idea... why wasn't it thought of before? The graphics and sonics aren't brilliant but the game itself could well grab you by the scruff of the beck and have you utterly hooked. From the Great Brickyard in the Sky someone or other is raining down bricks in your direction: you are trapped in a mega hole.

Your only hope of salvation is to jump on top of the bricks as they land, at the same time avoiding those marking straight for your nut, thereby eventually scrambling to ground level. Five more screens to play though!

You can only jump up one block at a time but you may slide isolated bricks about to construct makeshift steps: you may leap down from any height without incurring a penalty. By making the pit narrower each time round, the clever cloggs author has ensured it doesn't become too easy. But just in case, from level three the height of your wall is reduced from time to time by a whole row.

I said it was simple, but most people should find it addictive.
