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.

Happy 10th Anniversary Trism & AppStore

This game’s good even though I just started. I’m surprised it’s got the same menu buttons and the same old-version look as the iPod Touch, and it still works. The first app Game I ever got was Bejeweled 2, which is no longer available (Bejeweled Classic is still there); I had no idea about this game, and the fact that it was one of the first to be sold from the AppStore when it first opened back in 2008 (I found that out when its sequel came out after 10 years).

Awesome game

I love this game. No ads, no currency, just the game. I play almost everyday without having to turn off my wifi.

There are a few minor problems that can all be spotted by playing the game for 10 minutes (only like 3 problems) and those problems are easy fixes. Sometimes the triangles animations are moved out of place while moving rows. The numbers on bomb triangles will move way off. I forget the other thing, but now I have a suggestion to improve the game. The tilting feature is nice, but I think it should be automatic, but not make 3 or more triangles touch each other which would detonate a bomb if there is a bomb in play. If this is not something that will be done, I suggest that you instead give players an option to swipe the tilt icon to the direction that you would like the triangles to fall, not just keep track of the devices tilting. I want to be able to play this game without actually moving, like when playing in bed or while watching tv. I shouldn't have to constantly flip my device around just to keep bombs from detonating. Also, having the blinking colors that show the color of a triangles that you can't see is pointless and would be better if it simply stays that color.

Keep up the great work

Simple to learn, hard to master. Amazing game!

Trism is such a classic. The rules are simple but the gameplay is complex. That’s what makes Trism so great. It’s as simple and fun as bejeweled, but has depth that I haven’t seen in any other games like this.

I first played Trism when it came out 10+ years ago and recently downloaded it again. What a treat it is to go back to a game with fun core gameplay, no ads, and no in game purchases/currency.

I’m pleased that the game still runs on my iPhone XS Max. However time has not treated this game well. It looks very aged. The game won’t run in a resolution native to modern iPhones. The in game menus and alerts are from a different iOS era. Some controls don’t work properly, like the level select scroll list component doesn’t render the text for the selected level. But I’m still giving this game 5 starts because that doesn’t detract from the gameplay.

I tried Trism 2, and it’s a great game in its own right. But it doesn’t have me coming back to it again and again like the first Trism. What I’d rather see is a quality of life update for this Trism instead of a new Trism.

Overall it’s a great game. I recommended it for everybody.
