Hactar Go is often used to record a tournament game. Typically a player keeps a phone in the table, and records a move after playing them to the board.
Many players have commented that they are bit afraid they might accidentally start AI analysis when recording their tournament game. This would create rather unpleasant situation, even if one stops and disposes the analysis immediately.
Latest update of Hactar go adds a tournament mode. This mode disables and partially hides all analysis tools form game recording. This mode is a bit experimental, as there are many details that could be done better.
The tournament mode can be activated and deactivated only from the Hactar go settings. This is a bit temporary, I plan to make make a better UI for this. Also I will implement a history of tournament mode changes, so that one could show that the mode has been continously on during the game.
In the tournament mode Hactar go changes the toolbar color to the board color. This is intended to make it clear that Hactar go is in the tournament mode. If the phone is in the table, even the opponent can see this.
If someone is determined to cheat, tournament mode does not prevent it. Tournament mode is more against accidents and opportunistic cheating.
