Definitely easier than the normal Prize, which is of why I’ve finished it early enough to be worth posting! (And with only one hint from the forum)
FOI 12a, LOI 7d after I slipped into a rabbit hole - more below. COD probably 14d though many candidates. 10a a new word to me, and no idea why I spotted 13a and 15a as quickly as I did.
I wondered whether the theme should include computer games as well as card ones - IIRC, I only know 3d 8d as a version of 27a bundled with an early version of Microsoft Windows. With that in mind, I misled myself with a computer game that fits the Wordplay and crossers of 7d, although the definition is definitive. I’m not sure whether the ‘near miss’ thematic solutions have been mentioned, eg a 20a card, or the game hidden in 23d.
Altogether lots of fun, although less challenging than we are used to. thanks to Brummie and thanks for all your companion the forum.
