Allout is a puzzle that will truly put you through your paces. All you need to do is turn out all the lights on the gameboard. By clicking on a piece you will reverse the state of all adjacent pieces--from on to off, or off to on. If you're familiar with the classic Lights Out puzzles, Allout will be familiar territory, but prepare yourself for 50-plus boggling levels. Version 1.42 may include unspecified updates, enhancements, or bug fixes.
