Do I miss something or is it not possible to view the entire board?

No… you have to turn your phone and scroll.

Ouch I can't evaluate the board like that.?

Same with shogi, tzaar and polyomino and probaly many other games. My workaround for android is to use chrome and request page in desktop mode. Then the board is zoomable so you can fit it in the screen.

Toriodal go and morelli size 37 are also not good. The former looks like go11 or so but fortunatly 1 structure was impossble and only then i realized the difference.

also i have difficulty selecting a line for a move in dots and boxes. my thumb is too big.

pro tip: if your thumb is too big, use your pinky… or forefinger, but that's too mainstream.

I just lost a won game against an opponent rated 200 points above me because the line to click was too near to the  “resign”  button.

I definitely think the mobile interface should be improved

wow! a touch screen stylus works very well so far!

Have to go desktop to see if I am odd or even player
