Marble Master

You very quickly get to the point where levels cannot be won without paid items. Shots are "sticky" and will regularly hit stuff you're not aiming at. The background sometimes blocks balls and sometimes doesn't and it's not clear as to which is which. Some level layouts make it impossible to hit anything other than like 15 balls due to the "stickyness".

Fun game I used to play years ago, so I was very excited when it came across my feed. Unfortunately, it's quite irritating. Obviously, the developers make their money through running ads, but something is wrong in the programming. The game keeps crashing after an ad is played. If it's after a bonus round, you have to play the bonus round again and again. Very frustrating.

Yeah not a good experience. I played for 4 hours. Finished 40 v easy levels and the event unlocked. Why does by default the game fill up 70% of the screen. The event has 15 levels. After 25 games I'm done. I got to level 2 like 10 times but each time I'm overrun with 2s and 1s so when I try to break it's a net loss. Losing the level undoes your progress. Half the time I had 10 or more shots but didn't get any relevant colours. Not to mention all those enforced ads. Balance is good; Try it.
