About this game

A thrilling puzzle journey where mental math meets high-speed logic. Face an ever-changing 5x6 array of colorful spheres numbered 1 to 6, where every decision tests your quick thinking. Your mission: master the simple yet deep logic of addition. Select any combination of numbers that adds up to exactly "7" to trigger a spectacular burst, clearing the spheres and propelling your score toward the target!
But beware of the "Lucky 7" limit! One wrong calculation that pushes the sum over seven, and the spheres will shake in warning, resetting your progress and wasting your precious seconds. As the timer bar shrinks, the pressure mounts—you'll need more than just luck to win; you'll need the precision of a mathematician and the speed of an elite player. From the simple "3+4" to complex multi-sphere chains, every success is a rewarding brain workout. Dive in and see if you can claim the title of the ultimate Lucky Seven Master before time runs out!
