Family game night online is harder when the family lives in two time zones. One home is eating dinner while the other is waking up, and the grandparents' evening is the children's school morning. The games are easy to run from two homes. The hard part is an hour that works for both, and in a family it is usually decided by one person's bedtime. I will start there, then match the game to the length of the window.
Whose bedtime sets the hour?
Start from the hardest limit, because it decides everything else. In a family it is usually a child's bedtime in one home or a grandparent's early morning in the other. Then work in three steps.
1. Each home writes down the hours it can play, in its own local time, with the hard limit first. A weekend might read 10:00 to 20:00, ending earlier where a child goes to bed early.
2. Add the gap to convert one home's window into the other's.
3. Take the overlap. That is your shared hour.
Imagine two homes seven hours apart. Home A is ahead. If A can play from 15:00 to 19:00, that is 08:00 to 12:00 at home B. If B is free from 09:00, the overlap is 09:00 to 12:00 for B, which is 16:00 to 19:00 for A. Three hours of overlap is plenty.
The gap matters more than the date. This table shows where an evening hour at the home that is ahead lands at the other home.
3 hours; a's 17:00 to 19:00 is b's: 14:00 to 16:00
6 hours; a's 17:00 to 19:00 is b's: 11:00 to 13:00
8 hours; a's 17:00 to 19:00 is b's: 09:00 to 11:00
10 hours; a's 17:00 to 19:00 is b's: 07:00 to 09:00
12 hours; a's 17:00 to 19:00 is b's: 05:00 to 07:00
At 10 hours the slot is an early breakfast for B, which can work on a weekend. At 12 hours it does not work at all. Switch to A's morning and B's evening instead.
Do the clocks change on the same day?
Not always. Different countries move their clocks on different dates, and some do not move them at all. For a week or two each year the gap between your homes may be an hour more or less than usual. Check the gap in the weeks when either country changes the clocks, and write the time in both zones in the invitation.
Which game fits a short window?
Match the listed length to the slot and leave a few minutes for joining.
A 30-minute window: Trivia Tavern, about 14 minutes, plus a Quick Ludo of around five. That leaves a cushion for joining.
A 45-minute window: Who's the Spy at about 20 minutes and the quiz at 14, with a short break between them.
An hour: a Draw and Guess round of 20 to 25 minutes and Snakes and Ladders, listed at 10 to 25.
A long weekend afternoon: Ludo, at 30 to 60 minutes, or Property Rush at 45.
Allow for the family call itself. Open the video call first, send the table link there, and start the game when everyone has a seat.
Boardit also has Boardit Daily, five trivia questions that are the same for every home on the same day.
What if no shared hour exists?
Play at different times. Boardit Daily is built for it. Each person answers the same five questions, with 20 seconds a question, so a whole run needs at most 100 seconds of answering. Each home plays whenever it likes and sends the result to the family chat. There is a streak counter, and a button that shares the result.
One detail matters across zones. The Daily's day turns over at midnight UTC. For a home at UTC+2 that is 02:00 in the morning. For a home at UTC minus 5 it is 19:00 the evening before, so the new questions arrive at dinner time. Look up when it turns over where you live, and tell the other home.
Who hosts a game across two homes?
The home with the tighter window. The host opens the table about ten minutes early, checks the seats and sends the link in the family chat. Everyone else only has to tap it. Free online games like these ask nothing of a grandparent but a browser and a name.
Put the hour in both calendars
When you have found the slot, write it as two lines: the time at home A and the time at home B. Put both in the invitation and in each calendar. A call can fail not because of the game but because one home counted the hour wrongly.
