Expansion Modifier Chips

Two New Expansion Components

Doubler (left) and Inverter (right)

:::

Two new modifier chips have been added to Bossa: “Doubler” and “Inverter”. Each modifier chip performs the function of modifying the number or the colors of dots on a particular single tile.

It will provide more strategic and thought evoking fun for both frequent players and Bossa beginners.

Doubler: makes the number of dots on a particular single tile count double. (In the photo above, “White 2” is double counted to “White 4.”)

Inverter: Inverts the colors of dots on a particular single tile. (In the photo above, the dot colors are inverted, and “White 5/Black 1” becomes “Black 5/White 1.”)

2023 Revised Rules

With the release of the new edition of Bossa 2023, the game rules have been revised.
In the 2023 revision, the “(former) Advanced Rules” were renamed “Regular Rules” and the “(former) Basic Rules” were renamed “Novice Rules”. Based on the former rules, some minor changes (victory and tie conditions) and additions (clarification of handling of non-existent dot colors) have been made to the rules. In addition, an optional expansion rule has been added.
