Gave it a try, wasn't exactly impressed with it. No options to turn off the annoying music, in fact, apart from the 'small, medium, large' option at the start, there are no options. Cannot exit the game, unless you go 'Ctrl+Alt+Delete' and call up task manager, which then results in the cursor being stuck in a small area in top left of screen, so have to navigate the task manager with the keyboard. Was hoping it would be like all other 3 in a row types, where if it don't create a 3 in a row then you can't swap the gems. This version, you can swap pairs and move the gem where you want it regardless of it not creating 3 in a row. Also, unlike most 3 in a row, the gems don't drop to fill the empty space, new ones just appear in the space, so not really giving much of a challenge either. Also, you're not playing against the clock, so after a while, I became bored with the game. OK for a quick blast, but alas, with all these negatives, doubtful I'll be keeping it on the PC.

In Windows10 it doesn't work either. The same options as Lenny had played it for a while, but seems to be a continuous game, no levels.
I went with Alt-Tab to the desktop, started taskmanager and used the old-fashioned arrow keys to go to the game name and with 'e' end it (the mouse pointer went indeed to the upper left corner and stayed there shivering.

Uninstalled it as well.

Same experience as Lenny. Program, like others from this source, makes mouse unusable. Shouldn't there be a way to gracefully exit ALL games?

Downloaded on Windows 8.1 but it didn't work for me. Opening the game brings me immediately to the only options to chose from and those were the three different sizes of the game window: small, medium, large. I chose medium. For some reason I could hardly move the pointer to actually play the game. Also nowhere could I find the option to close the game or at least to close its window. Ctrl+Alt+Delete gave me the option to open the Task Manager but my mouse pointer became uncontrollable completely. I turned off my pc manually and afterwards uninstalled the game.
