OpenIdle
Read full descriptionHide full description
You've got a laptop, a credit card, and an opinion about AGI. Time to found your own AI lab. OpenIdle is a satirical idle game about the race to artificial general intelligence — and the way the finish line keeps politely moving. Found a company in a garage, train a model lineage, hire a workforce, generate hype, and allocate compute, data, and influence as you climb toward a post-AGI prestige loop. Hire, ship, hype, rebalance, and watch the target move with institutional grace. Cross an AGI goalpost and the definition quietly advances. Prestige, refound, and run the same race a little sharper. The numbers go up. The goalposts go further. - Bootstrap an AI lab from a garage to a sprawling research org - Train a model line with a personality — and opinions - Split compute, data, and influence across competing priorities - Ride market events, generate hype, ship on schedule - Cross AGI goalposts that refuse to hold still - Prestige into a faster, stranger version of the loop All companies and models depicted are fictional. The compute, tokens, alignment budgets, and moving goalposts they abstract are not. The treadmill, as far as we can tell, is perpetual.

Your hero fights, levels up, and collects gear on their own. You just check in. Grindcrawl is a retro pixel-art idle hack-and-slash RPG. Dive floor by floor, chase Rare and Epic gear, and reincarnate to go even deeper. HANDS-OFF BATTLES • Your hero fights monsters automatically and earns EXP and gear. No tapping needed. • Your adventure keeps going while the app is closed. Collect your rewards the next time you open it (up to a time limit, which you can extend). • Assign level-up points by hand, or let them be assigned automatically at a ratio you choose. DIVE DEEPER • Defeat five monsters to reach the next floor. Each new floor band brings tougher monsters and stronger gear. • Rare and Epic monsters are tough. With too little Defense, they may get away. • Past floor 300, a second area opens up with new monsters and new gear. GEAR THAT ROLLS ITS OWN STATS • Weapons, armor, and accessories come in three rarities: Normal, Rare, and Epic. • Every drop rolls its own stats, and higher rarities get more bonus slots. • Switch to Auto equip mode, and Rare and Epic gear stronger than what you have is equipped as soon as it drops. Or stay in Manual mode and choose for yourself. • Polish Epic gear with Shards of Brilliance to reroll its slots. Lock the slots you want to keep. • Equip two or more pieces of the same rarity (Rare or Epic) from the same floor band for an all-stat set bonus. COLLECT IT ALL • Defeat the same monster again and again to earn its Monster Medals, from Bronze to Platinum. Medals raise the chance of a gear drop when that monster appears as a Rare or Epic. • Donate gear to the Equipment Museum to fill its displays. Complete a Species Set for a big all-stat bonus. REINCARNATE AND GO FURTHER • The deeper you reach, the more Reincarnation Points you earn. • Spend them on permanent Attack, Defense, and Luck, more inventory slots, and a longer offline reward limit. Your gear, medals, and museum stay with you. MORE • Available in English and Japanese. • Get a notification when your offline rewards reach their limit. A few minutes here and there is all it takes. Check in, see how far your hero got, and close the app.
