Board Game Arena

In the French rules it is written:
"Quand un joueur passe, il récupère la carte Maison de plus petite valeur encore disponible au centre de la table et la place dans sa main.
Puis il reprend la moitié des Pièces qu’il avait placées devant lui durant ses enchères (arrondie au supérieur), les Pièces restantes sont retirées du jeu."
I bet 5$ and paid 3$. I should have paid only 2$ according to the rules.

Am I wrong?

Oh I can see that the English rules say the opposite...

There are several versions of the game available which use either the round-up or the round-down rule. Here on BGA you can create a game using either variant.

For what it's worth: according to Stefan Dorra, the game's designer, the rule should be to round-down (so you get back $2).

I used to play the game extensively with rounded-down returns, but when the new rules came out, I found them better, as they keep more money in the game and make bids higher and hence auctions more tense.
