We invite you to test your skills as a builder. Large wooden blocks will fall from the sky. And you need to build a big tower out of them. It's not tricky. But, if a block falls on the corner of the previous one, it can not only jump down by itself, but also destroy the entire structure. And, after all, it is its height that determines whether you can win and move on or stay at this level. Let's share a secret. In order to succeed, the following qualities are needed: attentiveness, concentration and calmness. Do not panic from the running seconds, calculate the right moment for the blocks to fall and victory will be yours!
