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.

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.

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).

Happy Trism Player

Thank you, thank you, thank you for the latest bug fixes, especially the one that prevented the Trism strips from being visible, which really affected play. I have been playing this game for years and was very sad when the game didn’t play correctly. So now I am a happy camper and would recommend this game, especially to people who like to compete against themselves to obtain their highest score. 😁
