Reaction Time is a free and addicting puzzle game by Tal Fishman, a YouTuber with over 3 billion channel views and 12 million subscribers. Go on a fast-paced and rewarding adventure through the solar system in a stolen rocket ship to earn power-ups as you build hand-eye coordination and mental acuity. Tap and drag the matching colored stars to clear the board and get the equipment and upgrades you need to reach the outer edges of space – but watch out, new stars are appearing constantly, so it’s a race against the clock!

Reaction Time is an adventure through the solar system and a thrilling race against the clock. Inspired by and created alongside the minds behind the popular YouTube channel, Reaction Time brings the same fast-paced, high-energy experience you’ve seen in their videos to your mobile device.

As Mr. Fishman, a professional satellite cleaner fed-up with the monotony of his job, you commandeer a spaceship and set out on a grand adventure to the outer edges of our solar system and into the unknown.

As you journey from the inner planets and toward the limits of the solar system, you’ll need to make upgrades to your ship and equipment by mastering six different beat-the-clock challenges on each planet.

Once you’ve mastered the challenges of our solar system, you gain access to the entire Reaction Time Universe, a super-secret playground of additional levels filled with new challenges and out-of-this-world rewards!

Your Objective
Earning the upgrades you need to continue requires matching shapes of the same color. Click and hold one shape, then drop it onto another of the same color to make them both disappear. Continue eliminating shapes of matching colors until the timer at the top of the screen runs out. Once you’ve beaten the clock, the two halves of the upgrade you need will appear on the screen. Match those to move onto the next level!

It’s not as simple as it sounds, though! New shapes are constantly appearing all over the board, and if the board fills before the timer expires, you’re out of luck and it’s Game Over.

Your journey across the solar system will be long and difficult, but there are three different in-game power-ups to give you the edge you need to succeed! Power-ups will appear on the grid for you to match, or they can be purchased through the in-app store.

LIGHTNING BOLT: Clear an entire column of shapes from the board
BOMB: Clear a cluster of shapes from the board
HOURGLASS: Freeze the timer for five seconds to buy yourself some time

Amazing Game.

I just recently received a notification that my pre-order has been fulfilled meaning that the app has downloaded into my phone. I opened the app on my home screen and I already could tell that I was going to LOVE this app. I don’t have much experience in the app yet saying as I just got it, but as far as I can see the graphics are amazing it actually includes Tal’s voice when you get past a level or so. Anyways this app is amazing and I really hope he makes more apps for people like me to enjoy.

Needs some fixes

For some reason when you want to play the first level it goes right to level 2 I figured out how to play level 1 but anyway the game needs some fixes when your outing the stars together it feels like you’ve been doing that forever and these other things pop up on squares and I have no idea what to do with them it didn’t explain at all what those things are but anyway it’s pretty good you just need to explain the game more when the player first opens it

Too repetitive...

I LOOOOVVE Reaction Time. I have been watching his videos for a long time. I was excited to get the game too. I just feel like it has some repetition when it comes to some of the levels. The tutorials are also way to long. I was getting kind of annoying to sit there for over a minute to play the actual game. I also feel like there is too much going on in the screen. It really confuses my eyes too. Overall, a few things to work on but I think this game really has potential!
