As a house rule, I'd consider making the game even more lore-compliant by adding the Interference Zone rule common to other versions of Sabacc to make play less random and more strategic:

INTERFERENCE ZONE: After playing but before the dealer rolls the dice, a player may take a card from their hand and place it in front of them face up, swap the card in front of them with another card in their hand face up, or place the card in front of them into their hand. Should the dealer roll doubles on the dice, the card in this Interference Zone is not discarded, and remains a part of their hand as long as it is in the Interference Zone. Only a single card may be in a player's Interference Zone at any time.

Thanks for the excellent mod, I'll be playing it next game night!

The way we've played is that instead of a fixed number of rounds, the game ends and hands are shown when someone takes their turn to call the hand. To do so, you give up the opportunity to draw/discard and instead simply call the hand. Then everyone left in turn order gets a last turn and then hands are revealed and a winner decided. The first few (2-3, agreed on by the table/house) rounds are safe (meaning you can't call on them) to allow for pot and hand building. We also play where you can draw once from either pile and discard once (only) in any order on your turn but can't pass (stand/do nothing).
