It has a little ads window on the side, and has Pay To Win or Watch Ad to continue. It also takes 235 MB of disk, full CPU core and 500 MB of RAM. Darn, Minesweeper for Windows 3.0 running on 8088 IBM PC didn't take all CPU resources.
𓀬 @k4gi@nina_kali_nina this is so weird . . . subscribe for one free continue every game ? it's, it's minesweeper, what's the point,
@k4gi this way you can get the experience that you need for the daily quest goals
