No pens. No paper.
Settings → The people you play with → type a name → +. You only ever do this once; they're there every night after that.
Tap a game on the Play screen, choose who's playing, set the options, and hit Start. Krooty remembers what you chose last time, so the second night is two taps.
In Tricks the kingdoms go round the table, so the order you tap the names in is where everyone is sitting. Start with anyone and carry on clockwise. The Seating list further down the setup screen shows you the order you've ended up with.
Yes. Tap the round, hand or talab on the scoreboard and re-enter it. Nothing is locked.
Krooty checks that a round adds up before it lets you move on. All thirteen diamonds have to go somewhere, all thirteen tricks have to go somewhere, and every queen needs somebody who ate her. In Complex play it also checks that the four penalties describe the same deal — somebody who took no tricks can't have eaten the King. The message under the Save button says which one is unhappy.
Somebody who has never played can be deleted outright. Somebody who has played can be retired instead — they stop appearing when you start a new game, but they keep every night they played and their place in the standings. Deleting them would take their results out of nights that were correct.
Both devices need to be signed into the same Apple Account with iCloud Drive turned on. Check Settings → your name → iCloud, and make sure Krooty is switched on. Sync can take a minute or two the first time.
Krooty respects the silent switch — a phone on silent stays silent, on purpose. Check the switch, then Settings → Sound inside the app.
Settings → Krooty Club → Restore purchase. It has to be the same Apple Account you bought it with. If it still doesn't appear, email me and I'll sort it out.
Yes. Its scoring has some genuine ambiguities I want to get right rather than guess at. If you play it and know the rules your group uses, please write to me — that's exactly what I need.
Card games have house rules, and Krooty is built from one group's. If your group plays something differently, I'd genuinely like to hear it — tell me the game, the situation, and what the score should have been.
