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.

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?

As long as as I can play…

I most certainly will keep this on my phone and play it until it no longer works on iOS. That indeed will be a sad day but it amazes me to see how I always come back to this game that never fails to be in my top favorites. If there is a way to keep this game going as a public service, WITHOUT CHANGING ANYTHING, I would certainly donate money to that effort!
