How to play Tiny Rex
Watch the path ahead and time your jumps and ducks to pass each obstacle. The run is about staying in motion for as long as you can. When it ends, save your score and try again with a better sense of the timing.
Tips for your next run
- Look ahead to the next obstacle instead of watching only the dinosaur’s feet.
- Choose a jump or a duck for the obstacle in front of you; jumping at every hazard will not keep the run alive.
- Use a few runs to learn the timing. Change one part of your approach at a time so you can tell what helps.
