Released on the very first day of the AppStore in July 2008, TRISM's legacy is one of rags-to-riches success. Created by indie developer Steve Demeter, the phenomenal success of TRISM allowed Steve to pursue his dream of game development. Steve's story has inspired developers all over the world, as told on Good Morning America, CNN, BBC, The New York Times, and others. Apple itself filmed a documentary on Steve, and presented it at the start of the iOS 3.0 keynote in Cupertino.

Great Brain Game


I am not a gamer by any means… But this is a game I have played for many years after I read an article about it in the business section of my local paper.

And it's a great game for spatial skills and overall just a nice way to occupy your mind when you need a distraction.

Play it Everday


My favorite IPhone game of all time. For would like to find playing tips and rules somewhere. I've tried.
Very satisfying to beat my old scores which happens more rarely now.
Would appreciate an update but it works on my IPhone 6

Wonderful game! 5 Stars!

Trism fan

I've been playing this for years and it never grows old! Best game I've found. I've had people ask what it is I'm playing after they've caught a glimpse of it in action.
