TwoGrid Blocks is a Tetris variant with a twist: you control TWO independent grids simultaneously. One thumb per board — both drop blocks at the same rate. The mechanic sounds simple. It isn't. As speed increases, coordinating both grids becomes genuinely addictive chaos. Built solo in SwiftUI. Free to try, one-time $0.99 unlock. No ads, no subscriptions. iPhone only.

Hey Product Hunt! 👋 I'm Chenglong, a solo iOS developer. I built TwoGrid Blocks because I wanted to answer one question: what if Tetris wasn't a solo grid, but two? The idea sounds like a tiny twist. Turns out it completely breaks your brain. When both grids are falling at the same time and you're trying to keep track of shapes on both sides — it's a completely different mental challenge. Built entirely in SwiftUI over a few weeks. The hardest part was making the dual controls feel natural — two independent D-pads, one per thumb, both responsive. Free to try (first 80 points). One-time $0.99 unlock for unlimited play. No ads, no subscriptions, no dark patterns. Would love feedback from this community — especially on the difficulty curve and whether the hook lands within the first 30 seconds. Thanks for checking it out!

Building it, I discovered the hardest design challenge isn't the code it's tuning the difficulty curve so both boards feel equally demanding. The moment one side gets harder, your brain locks onto it and abandons the other.
