Hi, does anyone know the rules to Zen Trek,please?

From my experience playing, the only different rule involves the circles with the brown semi circles. These have to be apart of zones and can’t be involved in a chain. Is this what everyone else has experienced? I don’t know what to call the circles with the brown semi circles.

Indeed the main difference is the brown semi circles (they are called the river) circles can't be in sequences/chains.
There seems to be a bug in this. If a number is part of a zone which includes a river-circle you can't connect a sequence to that non river circle.
However if you first connect a sequence to that non-river circle and then make them part of a zone with the river circle you can get it to work.
Odd that the ordering matters.

The other difference is that the map is 2x as large, and both sides have a separate 4x use of all operations. But that is quite clear from the map I think

Thank you,now it's clear to me
