Thanks JJ-Bug!!
Nice Kata!!
At first seemed quite simple, but not as simple as it seems!!

Fixed in Python.

.

He meant there is no fixed test like that and so, some wrong solutions pass. I see he has completed this kata in Java.

What language are you using? In Python solve_runes("1?*1?=1??") expects 0.

Tests in Python throw deprecation warning:

DeprecationWarning: non-integer arguments to randrange() have been deprecated since Python 3.10 and will be removed in a subsequent version
  x,y = rand(-1e4, 1e4), rand(-1e5, 1e5)

Fix

I see, thanks mate
