Suggestion:
The mine locations should be generated using a server secret plus a client secret this way the house could not cheat or pick the tiles at their advantage.
Just to add on this, in case LiveMines team decide to implement what you suggested.. The server seed must be generated and shared (hashed) with the user before the latter provides his own seed.
Thank you for your valuable suggestion. We do take it seriously. We have forwarded it to our team and will be looked into and implemented in coming updates if deemed alright for us to do so.
