Okay so I've gotten the checkmarks like ten times all separate games.I know that there are odds you won't get it,but still it should'nt take twenty times.
I have noticed that the odds a little better when it is the game of the day or of the hour. It also helps if at the first few levels you can get all three stickers in one play. I am not sure if I am explaining this clearly - if not let me know. Some days he just seems a little greedy with those trophies. Good luck & keep trying.
I have played that game a million times and have still have not gotten a trophy. I have watched the You Tube video and read all the hints, etc. I will try again when it is the game of the day! Good Luck with your quest!
I have also noticed that if you can get Booger to say "You're on the road to Math-a-matopia." Your chance of winning a trophy are much better. It still is not a guarantee though. I just play to level 6 when the card fills up. If I do not get a trophy I start over.
Somewhere on one of these posts I recently read that the odds are 1 in 50 when filling a card with checks to get a trophy. I play the game a lot and have gotten several trophies. I am not sure about those odds, but it does take filling a lot of them before getting one. Sometimes I fill a lot more than 20 cards without winning a trophy.
Also, you don't have to start over when trying to get a trophy. If you keep on going you can get one from filling a second or even third card. I didn't think you could but got one this week upon filling the second card all the way full of checks after not getting one for the first full card in the game.
The good thing is you can get a decent amount of KC while going for a trophy. Good luck. Blessings
