"How to Play" tutorial — four illustrated screens covering the goal, what a bid actually claims, how raising works, and when to call Liar or Spot On. Two of them are hands-on: practise a raise and try both calls with nothing at stake.
It opens by itself the first time you play, and it's always there from the main menu and the pause menu.
Solo matches now start with three opponents already at the table. You used to have to add them by hand before you could begin.
Your first three matches are against the gentlest opponents, so you can learn without being eaten alive. Random opponents after that.
Bid history down the left of the screen: who bid what, in order, so you don't have to hold the round in your head before calling Liar.
