Block Jai
Read full descriptionHide full description
Block Jai takes the classic 9×9 block puzzle and adds tools, monsters, bosses and progression that make every run different. Place blocks, clear rows, columns and 3×3 areas, build combos and plan ahead to keep the board alive. When things get difficult, your tools give you another way out. Use Dice, Hammer and Rotate strategically, and unlock perks that change how you play. Want more pressure? Enter Challenge Mode and face unique boss stages with their own mechanics. Choose how you want to play: • Normal — the core Block Jai experience • Impossible — built for tougher runs • Challenge — take on bosses and special objectives Compete through Game Center leaderboards, improve your best scores, earn rewards and keep building your strategy. Simple to learn. Much harder to master.
