Simply fill in the fields as the numbers come.

6x6 fields are reserved for area 1 to 36. The upper line is for 1 to 6. And so forth and so on.

A kind of deadline: End the session if there are only seven blank spaces left.

Eeeeeeexactly four fields in a row means something. Four fields filled in that is.

It means that we get a hit with one chip on the winning number.

It might be four fields in some horizontal line, say 14, 15, 16, 17,

four fields vertically, say 18, 24, 30, 36.

Or four fields that could be reached with A BISHOP from the game of chess,

e.g. 1, 7, 15, 22 or 6, 11, 16, 21.

The number of possible combinations do not differ. The pattern of exactly four in a row in the horizon is exactly as probably as four in a row vertically or four in a row with the Bishop

My goal is "two out of three": With the Bishop, Vertically and/or in the Horizon. Only two hits. After winning for instance with the Bishop, so to speak, I focus on the other two levels for the rest of the session, until I get one hit there or collide with my deadline.
