Tetris meets Sudoku
Tetris meets Sudoku. This mind-bending puzzle game is easy to learn but difficult to master. Compete globally, challenge your friends, or simply compete against yourself as you continually chase a higher score. Addictive, rewarding, and one of those rare games you’ll keep coming back to.
I’ll just play one more…
This game hits the sweet spot between relaxing and challenging. The rules are simple, but there’s real depth once you start planning several moves ahead. It scratches the same itch as the best classic puzzle games, but still feels fresh.
Addicting!
Once you start, you can’t stop. Love the game # count and personal leaderboard. Plus, the ads are not as much of a nuisance as they are on other gaming apps, which makes playing all the more addicting.
Super addicting
This game is really addicting. It took me a few minutes to realize stacks can go horizontally too and now I’m determined to get on the leaderboard
Fun and sharp
It’s a fast, fun, sharp and quite compulsive game- I found myself feeling the need to work harder to get smarter moves. And there is math. A good way to take a different type of phone break.
Addicting Challenge
This is my go-to for my commute! So fun. Also: how am I so bad at this game. Am I stupid? I hope not - because I am a scientist. Awesome game!
Addictive!
Once you get the hang of it it’s a blast
Super Fun
A game full of strategy, yet easy to pick up and learn… the challenge lies in analyzing and improving how to best eliminate other sphere’s with the given numbers, it’s a fun game to keep on learning while the “surge” factor keeps it exciting

New Brain Game
I can see how this can become addictive! The hard part is learning the game but it gets easier before it gets harder again. I don’t play other games so most of this is new to me (older generation!)
Addicting brain workout
I downloaded this new game try something new. It reminds me a little bit of sudoku but way more fun. It also feels more addicting than Candy Crush. 😆 Glad to know there’s some cognitive benefits!!
Brain Blast!
Spark7 is a great brain teaser, entertainment game. The ‘how to play’ is clear and concise and once you learn it, you’ll be hooked. Time to stop doomscrolling on Instagram and play!
Super addictive!
Love this super compact puzzler. It's deceptively simple, with very high replayability. Hard to put it down!
Boom!
Great exercise for the brain! Lot of fun as well.
Awesome game!
Great mental workout of a game. I play this every morning when I wake up to get the mind going. Highly recommend!
Puzzle game of our generation!
Spark-7 is one of the most unique puzzle games I have ever played. The exact-match mechanic makes every move matter, and the chain reactions are very satisfying when you set up a big chain reaction. I like how there’s no timer, so you can actually think through your strategy instead of rushing. The game is challenging to learn but get surprisingly deep once you start planning around stones, discs, and future rows. If you enjoy puzzles games that reward careful thinking, the this is definitely worth trying!!!
