Eoroid - Pattern Puzzler

Your goal is to remove all blocks from the board. Clicking on a center of given block-pattern - reverses all it's fields. So empty ones become full... and full ones become empty. As game progresses - different block-patterns are available. You can train by toggling Time/Move limiters... and of course You can play without any of these constraints in normal difficulty as You wish :) Your score is converted to credits - which You can use to replay levels.

Nightmare > Time and Moves limiters are always ON > You gain 1 credit for each 3000 points scored > Each stage has 15 levels > Level grid is bigger than in normal/hard difficulty > More complicated levels than in hard difficulty > Less moves / time than in hard difficulty
