Synchronization bug that sometimes starts parallel live games

I like playing fast live games where it isn’t meaningful to play two games in parallel.

When I have a game offer running in the game.list and choose to accept a game another player has offered, normally my offer is terminated at that moment.

However, this is not stable. Every when and then, I end up with two games in parallel. On a smartphone screen, there is no real way to handle them, I only can detect them by the number of open moves displayed (as I normally don’t play correspondence games). I even encountered this problem in the middle of a game. This is annoying for the other player that just sits around waiting in the parqllely game. And if he really waits until timeout, I get the educational message to play in my games, threatening with additional sanctions.

I would appreciate a stable synchronization mechanism that only starts one live game at a time. If things happen to overlap, the player who wants to start the second game could get a message like “this challenge does not exist anymore” (what you get if you accept an offer that just has been accepted by another player).

Thank you for fixing this.

@anoek do you think the recent related fixes will deal with this one?

If you delete game offer you created first and only then accept game offer of other player, 2 games will not happen.


it’s possible to hope for better interface, it’s also possible to do additional safety measures yourself anyway

The one I fixed was related to rapid automatches - @Tofuwok , when you have a game offer running, are you talking about a custom game or an automatch game?

Custom game.

I recently had the problem several times. Situation: I have a custom game offer running. After some additional players offer their games. I challenge one of them directly, he accepts and some moves later the other game starts.

That looks to me that it is not a timing issue. It looks like there is no auto-removal of open games at all.

What is the current philosophy of OGS: Should players be able to play live games in parallel? There was a warning introduced when switching from a game to the Lobby or other page and also it is not possible switching games via the number of open moves at the top. This indicates that parallel games should be prevented. Maybe you could make it configurable. I clearly would opt for having only one game at a time.
