Thank you for suggestions, they are very helpful.
I don’t understand the second part. what is “two fields affect the result of another”?
Currently the fields end being [seconds vs seconds] or [hours vs minutes] with each betting one card from their side; A functional variation could be two spots for the same value (like minutes) against 1 of her spot;
Would look something like [minutes minutes vs hours] or even [days vs seconds weeks]
I imagine it would take more work to adjust something like that, but it's an idea. Hope to have explained myself better
