Quadrum!

Quadrum! is a fast thinking game designed to test your skills in various ways. The four game modes will each challenge you differently.

- In mode 1, speed is not always the answer, because the only thing that matters is the highest score.
- On the second mode, though, speed is the answer. You’ll have to be quick to get the first place!
- The third mode will take your memory skills to their limit.
- Finally, on the fourth mode, your speed and focus will both be the key to survive for a longer period of time!
- And a secret challenge, can you find it?
