Game Rules: Qwixx

Game Identity

• Name: Qwixx
• Player Count: 2–5 players. Standard: 3–4.
• Teams: No teams. All players compete individually.
• Theme: Commercial dice game by Gamewright. Players simultaneously mark off numbers on a 4-row scoresheet. Points increase the more boxes checked per row; penalties apply for passing on an active turn.

Scoring Mechanics

• Scoring Variant: Accumulative (with a non-linear per-row bonus structure).
• Target Score: No fixed target — game ends when 2 rows are locked or any player has 4 penalties. Highest total wins.
• Unit of Scoring: Points based on boxes checked per row (triangular number progression).
• Lower vs. Higher: Higher score wins.

Rules & Validation

Scoresheet Structure

• 4 rows:

  • Red: numbers 2–12 (left to right)
  • Yellow: numbers 2–12 (left to right)
  • Green: numbers 12–2 (right to left — descending)
  • Blue: numbers 12–2 (right to left — descending)

• Boxes within a row must be marked left to right — you can skip numbers, but you can never go back.

• Row Locking: To mark off the final number in a row (the 12 in Red/Yellow, or the 2 in Green/Blue), a player must have at least 5 boxes already checked in that row. Locking the row earns an extra check mark and closes the row permanently for all players.

Scoring Per Row (Triangular Number Formula)

Checked Boxes	Points
1	1
2	3
3	6
4	10
5	15
6	21
7	28
8	36
9	45
10	55
11	66
12	78

(Formula: n × (n + 1) / 2 where n = number of boxes checked)

Penalties

• Penalty: −5 points each (max 4 penalties). Taking a penalty counts as the player's entry for their active turn.

Game End Triggers

• 2 rows locked (by any combination of players), OR
• Any player marks their 4th penalty.

Validation Rules

• Each row's box-count is monotonically increasing (can only gain boxes).
• Locked rows: enter the final locked count (adds +1 to the row's check count for the lock bonus).
• Penalty count: 0–4 per player. At 4, game may end.

Win Conditions

• Condition: When 2 rows are locked or any player reaches 4 penalties, all players finish the current round. Tally total scores (sum of 4 row scores minus penalties × 5). Highest total wins.
• Tie-Breaker: Most boxes checked across all rows. If still tied, fewest penalties.
