This number puzzle challenges you to prove that counting to ten can still be tricky. A square grid is filled with cells holding values from zero to nine, and your goal is to connect them with a finger or pointer into chains that add up to exactly ten. Drag through neighboring cells to draw a path, release when the sum looks right, and every number in a correct chain drops by one while any zero included in it vanishes from the board. The faster and smarter you play, the more points you earn from the time you have left. There are three levels of growing difficulty, each using a larger grid than the one before. Every level gives you ten minutes to clear the board completely before moving on to the next challenge. Watch the clock, plan your chains carefully, and keep the grid from overflowing with numbers.
