Portuguese casinos stop french roulette. Now only american roulettes, baccarat, black jack, french bank and poker tables. So several coloured jetons were retired- for baccarat and french bank they only need to use one colour of each value, and they do it.
For american roulette some casinos don´t use house chips ( but chips with boats, anchors, etc).
American style chips are used in poker and black jack.
