After Solitaire, what's likely the most played game on your computer if you're a Windows user? Minesweeper. And like Solitaire, it's a trusted favorite for spending a few minutes in between other tasks or while waiting for your friend to get off the phone, and like Solitaire, it gets pretty dull after awhile. There's plenty of different versions of Solitaire out there, but different versions of minesweeper? How can you change that game?
How about instead of mines, the things that are hidden in the blocks are actually monsters? And instead of trying to avoid the monsters, the goal is to defeat them? That's the idea behind this Japanese version of Minesweeper called Mamono Sweeper, which you can play online for free. You start out as a level 1 adventurer who can only defeat level 1 monsters. As you explore the board and defeat a number of level 1 monsters, you gain a level yourself and now can defeat level 2 monsters. The site has several different board size and total monster levels. I prefer the "Huge" game, which goes up to Level 9.
It's by no means a perfect game. The biggest flaw I have with the Huge game is that to be perfect, you have to identify everyone of the Level 1 through 5 monsters before you gain level 6, and then you subsequently have to identify all the level 6 before gaining level 7, etc. This lack of flexibility in the later levels is frustrating, as you strain your eyes reviewing and reviewing the board to try and find that one monster at level 5 you missed.
But, for a free twist on a classic, Mamono Sweeper is a great timewaster. I warn you, though, don't bookmark that site, or you may become addicted to this simple little game.
