I saw the ad for this while playing another dice merge game. I thought “what the heck” and downloaded it and boy, am I glad I did!! Way more challenging than I thought, what with the dice that you have to put in that are angled! I saw another review where the person said you can very easily lose track of time….believe me, it’s true!! To actually stop playing is the real challenge!! My only “complaint” would be the ads, but considering it’s a free game, who am I to complain?? 😀😀 If you want a really fun and very challenging game to pass the time, get this!! Oh, and don’t forget, time flies!! HAPPY MERGING!!
