@typhlosion if you haven't tried it before, there's a really good solitaire app on android that's just called "250+ solitaire collection": https://play.google.com/store/apps/details?id=com.anoshenko.android.solitaires&gl=US
one of the few timewaster apps we've liked enough to pay for

@typhlosion recommendations in that: all the usual ones (freecell/forecell, variants of spider, klondike, etc), but also blockade, busy aces, algerian patience, queen topsy-turvy, american toad
it also lets you make custom games and we've made one or two simple variants that are enjoyable
we like the ones that you can usually win
