I am jealous, mine are still sitting in the queue. Last year it took almost a month.
Which day were you able to release the holds?
For impulse, I will guess some of the smaller ones since we tend to take more risks with those. Canvas and Radlands perhaps? (Both of those are great btw) And maybe Splendor Duel, guessing you already had regular Splendor so you were hesitant about getting Duel too.
I was able to release on the 14th, maybe a few minutes after 12 their time. One of the lucky ones!
And yep all the small ones were impulse. I’ve never played any version of Splendor but heard great things about duel, and at ~$13 pfft that’s basically free.
