Board Game Arena

I've checked the rule and it seems there is no tie breaker in Russian Railroads.
But BGA makes the tie break.
On which basis?

Can you point to a table in which a tie-breaker was applied for Russian Railroads?

I assume the original poster is thinking of tournaments, since regular or arena don't have a tiebreaker. I agree that the tournament rules for breaking ties in bracket tournaments where the top 1 or 2 from each game advance are confusing. That's a BGA question rather than a Russian Railroads question though.

yes that's it: tournament tie-breaker
