You always make at least one fake point per second. You can use fake points to add 1 to the buttons in the grid. The button values add up in rows by multiplying each other and in columns by adding each other. You can't use columns to the right until every button in the column before them is at least 1.
It costs fake points to add 1 to a button in the gridand this exponentially increases each time you add 1. If you don't like how long you're having to wait, you can spend 1 real point to return the cost back to 0.
Once you run out of real points, the button to buy more will enable. This does not cost real money though.
