What Makes XXI: 21 Puzzle Game Stand Out
XXI puzzles require a sum of 21 in every row and column. Move the gems around on the board until a solution is found. All gems have a unique numerical value, but watch out for the special gem that can be either a 1 or 11. Puzzles get harder as you progress your way through all 200 levels. Can you become a XXI champion?

Community Insight:
Really good puzzle game. We can not stop playing. Download it now.
Fun and challenging without being frustrating. A little easy to start, but by the 100th level, it starts to get interesting.
TM Soft does it again with an addicting and challenging game that keeps us entertained in waiting rooms, passenger seats of cars, and at work.
Really addictive platform that made us lose time and stay up waaaaaay too late. Save some for Dad now.
Reminds us of a bar top game we used to play in our younger "bar cruising" days. Oscar said it was good, and we have to agree.
We like this sort of game. Gets us thinking outside the box.
TMSOFT has a suite of really fun games. XXI continues in this trend with a fun and original game. We enjoy relaxing and figuring out the pattern.
Another Fluoride free addictive game from tmsoft.
Once again TM soft has put out yet another reason for us to lose sleep and productivity at work. Todd and his crew of masochistic lunatics really thought this one out and came up with something even better than compulsive we can't recommend this game hire for anyone who has time to kill.
We thought compulsive twisted our brain in a knot, wait until you play this! It's just like when a bar cooks your wings crispy enough.
Another great game from the people who brought us White Noise and Compulsive!! We can't seem to put it down. It has "peeksa" our interest.
We really enjoy this game reminds us a little of soduko. It's a classic puzzle game that will keep your brain turning with questions and strategy. Fun time.
