I am playing a game now a days that’s “Soukoban” – a brain teaser/twister game. Its a maze type game. You have to search your way in maze. It has 100 levels. Even initials are not so easy in it.Till today i have reached its 79th level … by the way 12 days before i had started playing it. First time i got stuck at 10th level that took 2 and 1/2 day to get it solved.Later on 17th,32nd,39th,42nd,47th levels it took long time to solve it but after 50th level it became complicated and after 60th level its damn complicated. For 60th onwards levels you have to make your predecided strategy to solve the game up to the fag end of current level.On even a single mistake you can’t be back means you finished, cant play ahead for that level.It’s really brain twisting. Behavior of game is totally not instinctive. You will have to make a strategy at the beginning, see all abortion reasons on every nook and cranny at the beginning then start playing otherwise you will surely loose the game specially after 50th level. Playing this game i have felt in myself my speed of doing something related to brain has raised. Surely you will measure in yourself rise of speed & grasping power.You can get it from this site
