make a time duration!
Game starts with 10 seconds but every time a player makes a move the file of the piece’s new location is added to that player’s time (e.g. White has 4 seconds, white moves queen to b4, white now has 8 seconds)
Both players use the same clock and if the clock runs out than both players lose
You can only win by checkmate

Rapid, but when you're winning and it's your turn, there's a chance of you losing 2.5 minutes.
ManageTime
You have 10 clocks, each with an independent timer, you can change which clock you are using on your turn, it costs 1 minute on all of your clocks to change clocks and you cannot do it more than once per turn. If you run out of time on any clock, active or not, you lose on time. If you run out of time on all clocks, you get an achievement.
