WYPS LG docs - misleading rules for numeric variant

I believe LG-docs for WYPS (numeric variant) are misleading

WYPS LG-Docs: Variants on Little Golem

There is also a numeric version where the letters are replaced by numbers. You must play even numbers or sequences of numbers.

Shouldn't it be ...You must play same number or... ? As far as I know even numbers are the ones divisible by 2 (2, 4, 6, ...)

Yep, just a translation problem I guess.

Yes, I would have used the word "equal", but really "equal" and "even" are synonyms in many contexts, including (almost) this one.

I've now tried playing numerical WYPS, where a valid word was when the sum was a certain number. I always played size 8 which is 36 stones, 6 sets of numbers 1 to 6. I tried sums from 7 to 12. Probably the most interesting game was at a sum of 9. I find that version better than the one that is now implemented.

As a mini version, I then tried size 5 (numbers 1-4, sum 6).
