How to buy 50 technology levels

When buying technology levels, you are able to buy specific amount at a time, the minimum amount being 0.5 level and the maximum being 10.0 levels. You can save money by buying technology in a specific pattern for your first 50 levels.

The pattern is as follows:
4.5 Levels
10.0 Levels
10.0 Levels
5.0 Levels
10.0 Levels
10.0 Levels
0.5 Levels

This pattern is cheaper than buying 10.0 levels five times.

The game has increased the number of infrastructure levels you can buy from 50 to 100. I don't currently have a buying strategy ready, but I am working on it. Check back here for out-of-date updates.
