Everyone plays the same hole at the same time. Other balls are
ghosts — unless the host switched ball collision on,
and then every ball standing still is solid: hit one and it rolls
away. Being knocked costs you no stroke, water included, but a
knock into the cup counts.
Pull back to aim — the further, the harder. The dotted line
shows the path to the first bounce.
Red bumpers kick, sand slows, blue strips push, portals swap
you to their twin, green arrows are one-way gates.
