Objective

- If the two sum to the target value, both clear and new blocks fall in.
- Clear the target number of pairs to win.

About Digit Drop
Digit Drop fills a five-by-five board with digits from one to nine and challenges you to find neighbors that add up to ten. Select one block, then an adjacent block, and if the pair hits the target both disappear and new digits drop in from above. Clear eight pairs to win. It is a quick mental arithmetic game with a satisfying cascade as the board refills.
Tips and strategy
- Memorize the complements of ten: one and nine, two and eight, three and seven, four and six, and five with another five.
- Only blocks that touch horizontally or vertically count, so diagonal neighbors are not valid even if they add up correctly.
- Remember that blocks fall after a clear. Clearing a pair low in a column can bring a new digit next to a partner you were waiting on.
- Scan whole rows and columns rather than staring at one spot, because the best pair is often at the edge of your attention.
- Stuck on the board? The Highlight a Valid Pair button points out one possible move, and tapping a second block that does not match simply starts a new selection.
What it exercises
Digit Drop trains number bonds, quick mental addition and visual scanning. Because the grid keeps changing as blocks fall, it also encourages flexible attention, where you keep checking for new opportunities rather than following one fixed plan. Steady practice makes those number pairs feel automatic.
Frequently asked questions
- How do you clear blocks in Digit Drop?
- Tap one block and then tap a block directly beside or above or below it. If the two digits add up to ten, both are removed and the columns drop down.
- How many pairs do I need to clear in Digit Drop?
- You need to clear eight pairs. The counter above the board tracks your progress, and the game ends in a win as soon as you reach eight.
- What if I pick two blocks that do not add up to ten?
- Nothing is removed, and the second block becomes your new selection. There is no penalty beyond a counted move, so you can keep looking.
