What are modes ? Modes are leela playing at different playouts, which can be compared to nodes in traditional chess engines.
In normal mode, Leela is playing very fast and can miss tactics and mates, but it is the simplest way to see how she behaves.
In hard mode, Leela should play much better, but it takes more calculations so you will have to wait 5 seconds after she answers not to overload the server.
In easy mode, Leela is not doing any calculations and is playing purely by insight, just taking the board and evaluating what looks interesting.
