Good mobile games to play during the day in quick sessions - If it's turn-based and/or card game like Slay The Spire, all the better

First, happy new year to you all!

With two jobs in marketing & communications and almost 40, I've come to a sad but inevitable conclusion. And I know it's a paradox, but the only time I can play games is during work. Because while I'm waiting for task approvals or meetings, I can run some quick sessions on my phone.

So I'd like your help in suggesting me your favorite games to play in these conditions, preferably card games (I already know Slay the Spire, Balatro, and Pokémon TCG Pocket), strategy, turn-based RPGs, etc. If you know any great emulators for old games, I'd also appreciate it (with no ads, please, I don't mind paying a decent price for them).

And no gacha, please (although I know, it's the norm for mobile games). I've tried DB Legends and FFVII Ever Crisis because I'm a fan of the sagas, but I find these kinds of games unbearable.

Thank you very much!
