Cool, always interesting to see someone play your game! You kept trying to do the sideways placing "the wrong way" around. Makes sense that it would work that way too. But this didn't even cross my mind as normally as far as I remember in dominos you can only place normally and sideways at the tip of a bone, here the rule when you're allowed to play sideways is just different.
Hope it didn't feel too frustrating with the constant "why can't I place this here". 😅 Most of those indeed were pretty obvious to me at least but there indeed were some cases where one could reasonably think that should be allowed.
Thanks for playing! ❤️
