About this game

This electric number puzzle will rewire your brain and may make you miss your bus stop.

Spark7 is like Drop7 on steroids – as if Tetris, Dr. Mario, CandyCrush, Sudoku, and 2048 got together and had a baby to become even more satisfying and engaging.

The gameplay seems simple at first. Just drop numbered balls into the grid, match them by count, and chain explosive combos (“surges”) to boost your score.

But very quickly, you’ll find yourself gradually understanding the game’s hidden nuances over time, continuing to improve your skills and your brainpower during every moment of play.

You’ll also find yourself obsessing over the global top scores for each individual Game ID, and cranking your “replays” to work up the Leaderboard.

The best part is that Spark7 was created by a literal brain scientist. Each game mechanic is meticulously crafted to exercise your spatial reasoning, working memory, executive function, processing speed, attention span, problem solving, and mental resilience.

If the disappearance of Drop 7 left a hole in your puzzle life, Spark7 fills it — and then some. This is the number drop game you didn't know you needed.

Download Spark7 and light up your brain.
