10x10 games are some of the most relaxing yet mind-bending puzzle games out there. Like all good puzzles, the premise is easy but the play is not. Each round starts with a blank 10 by 10 grid. Pick up the blocks given to you, and move them somewhere in the grid. Try to fill up straight lines horizontally or vertically to clear away the blocks and collect points. This frees up more space. You don’t know which blocks you’ll get next, so you have to be careful. Maybe the next set of blocks will all be very big, and you won't be able to squeeze all of them into the grid. If you can't make your blocks fit, you'll lose the game. Try not to back yourself into a situation where the grid becomes too cluttered or crowded, or you might find yourself running out of space. If you allow the grid to fill up too much, your game won't last very long. At the same time, clearing multiple rows in one go results in a big bonus reward. Weigh the risks and see how long you can keep filling up the grid in this fun collection of free online 10x10 puzzle games.
