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.

Addictive and fun!

I’m notoriously cheap and not one to buy games very often, but this one is definitely worth the price! Once you get the basics, you will NOT be able to stop playing! The game can get frustrating, but that’s part of what makes it challenging and awesome. I haven’t reached 1,000,000 points to unlock the Starshine mode yet, but I hope to reach it soon! If you buy only one game, Do yourself a favor and get Trism, it’s worth it! Looking forward to trying the sequel also! 😊
UPDATE: I’m dying to try the sequel, but there is only one level available. When can we expect an update on that?


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).



Still a go 2 game 4 me. 😊 Definitely 5 🌟 all the way 4 withstanding the test of time. I have 1 favor 2 ask; can u PLEASE remove the banner advertising “Now Available, Trism 2!” It’s NOT. Not in U.S. appstore anyway. I clicked on that banner & it goes 2 the app store but a “Not available in U.S. “ It may b a little thing, but it REALLY annoys & irrit8s me when something “unavailable” is advertised as if it is.
