Silicon Evolution vs Ironhold

Start with a single 8-bit CPU. End up running a quantum supercomputer. Everything in between is up to you. Silicon Evolution is an idle game about building a computing empire across 8 technology eras. Buy hardware, invest in research, prestige to keep your gains, and come back to find your empire still ticking away while you were gone. The research tree has 122 nodes across 11 categories - power, cooling, networking, security, virtualization and more. Each node has 5 levels. It takes a while to work through all of it, and that's kind of the point. Once you hit the 32-bit era, you pick an architecture path that sticks for the rest of the run: - Overclocker: your cycle output goes up 60% and the Boost button lasts twice as long - Architect: knowledge generation goes up 80% and research gets 40% cheaper - Resilience: offline earnings jump 120% and your legacy hardware earns 3x as much Prestige resets your hardware but not your silicon shards, which permanently multiply what you earn. Each run is a bit faster than the last. After enough runs you can reset everything for a leaderboard time and try to beat yourself. Old hardware never disappears - it becomes legacy income that keeps paying out forever. No paywalls. No timers you can pay to skip. The only in-app purchase removes ads, and that's it.

One castle. Endless waves. Every rebuild starts stronger than the last. Ironhold is an idle tower defense set in the world of Thornveil, where you command a single keep across an unending siege. Place your defenders. Route your gold. Watch the walls hold — or don't. When the keep falls, the coffers fill, and the next siege begins stronger than the one before. This is a game of small decisions that compound. Every coin picks a lane. Every upgrade sharpens the loop. Every run teaches you where the walls will break next. WHAT YOU'LL DO — Defend across endless waves. Wave 40 is not the end. Wave 400 is not the end. — Recruit from eleven great Houses. Fifty-five named defenders at launch, each with their own strengths and their own price if they fall. — Route your gold across attack, defense, and support. Every siege is a new economy. — Rescue what the walls take. When a defender is captured, you can send others to bring them home. — Return to progress. The keep works while you're away — resources, waves, and stones accumulate offline. WHAT MAKES IT DIFFERENT — The roster stays with you. Named defenders level up, remember their wounds, and carry your history across every run. — The Veilwatch turns each week. New invasion scenarios, new leaderboards, new pressure. — Twenty-eight artifacts to unlock, each one bending the siege in a different direction. — No timers standing between you and the next decision. Ironhold is built for players who want the depth of a strategy game and the pace of an idle one. The walls will fall. That's part of the loop. The chronicle is what you build across every rise and ruin. Hold the line. Rebuild higher. Contains optional rewarded ads and in-app purchases. Both are entirely skippable. — Get It Got It Games
