Put your ideas and reflexes to the test in Battery Stack PRO, a falling-block action puzzle with batteries of different sizes and shapes. CONNECT BATTERIES AND START CHAIN REACTIONS Move and flip falling batteries to line up their terminals. Connect three or more batteries with matching terminal colors and opposite polarities (+ and −) to clear them and earn points. Plan your stacks to set off satisfying chains, with sparkling effects and explosive animations. A CHALLENGE THAT KEEPS GROWING The score for clearing a battery depends on its type. As your score rises, batteries fall faster. Starting at 200 points and every 200 points after that, faster obstacle batteries appear. When they settle, they explode and trigger chain checks, adding a new twist to your strategy. TOUCH CONTROLS Tap the left or right side to move, the bottom third of the screen to speed up the fall, and the center area or bottom controls to flip the battery. DIFFICULTY PRO is the paid, ad-free edition. Choose Super Easy (two terminal colors), Easy (three colors), or Hard (four colors). The free Lite edition offers Super Easy only. GAME OVER The game ends if a battery settles in the hidden area above the top of the field. Make quick decisions, build clever connections, and chase a new high score!
