Once again I try to keep it :scratch_ones_head:simple. For each session I need a grid (6x6). The first line contains 1-6, the second line contains 7-12. Etc.
When I win, an isolated number has just been united with a group. An example from the first line: 2, 4 and 5 came. I bet that 3 comes to unite 2 with 4&5. If, however, 1 comes before it happens, 2 is no longer isolated. So the line must be abandoned.
There are six horizontal and six vertical groups of six in the grid. I chase the pattern in each of them.
The sessions ends, if only seven of the 36 numbers have not come.
