Offline AI block puzzle — train your neural pet, duel it, watch it think.
Meet Cubrix — the block puzzle where the AI lives on your phone, not in the cloud. Cubrix is a classic 8x8 block puzzle with a twist: a real on-device neural network learns from every move you make. No wifi? No problem. This is a true offline AI game — every duel, every training step, every decision runs 100% on-device. 🤖 TRAINABLE AI COMPANION Your own neural pet watches how you play the block puzzle and trains itself on your moves. The more you play offline, the smarter your AI becomes. It is not a scripted bot — it is an on-device neural network that adapts to your personal style. ⚔️ REAL-TIME DUELS — YOU VS AI Challenge your trained AI to a duel. You and the AI get the same pieces — who scores higher? Duel your own creation, punish its mistakes, and watch it counter-train on the duel you just played. Every duel makes the next one harder. 🧠 DECISION LOG — WATCH IT THINK Open the AI Lab and read your companion's decision log: why it placed that block, what it predicted, where it blundered. No other offline block puzzle lets you watch an AI think — and then exploit its weaknesses in the next duel. 📴 100% OFFLINE — NO WIFI NEEDED The AI trains and duels entirely on-device. No wifi, no data, no cloud, no account. Play on a plane, in the subway, anywhere. Your neural pet never leaves your phone — and neither does your data. HOW THE TRAINING WORKS Play a game — the AI watches. Finish it — the on-device neural network trains on your moves. Skip a day — it keeps what it learned. Everything stays offline on your phone: no uploads, no sign-in, no wifi at all. Want a fresh start? Reset the AI anytime and train a brand-new neural pet from zero. 💎 CLASSIC 8X8 BLOCK PUZZLE Under the AI there is a polished block puzzle you already love: drag blocks onto the 8x8 board, clear full rows and columns, chain combos, chase Perfect Clears.
