Rummykruss Rule Book

Overview

Rummykruss is a Rummikub-inspired game played on a crossword-style 2D grid. Players create valid sets and runs, scoring points for intersections. The game has two phases: a Setup Phase for drafting tiles and a Gameplay Phase for placing them.

Components

• Tiles: Numbered tiles (1-N) in multiple colors (1-C).
• Wildcards: Default 2, can replace any tile.
• Game Grid: Default size 15x15, includes X random blocks that cannot be placed on.

Objective

Score the most points by forming valid sets and runs while maximizing intersections. Use block-locking strategically to limit your opponent's options.

Key Terms

• Set:
  • 3+ consecutive numbers, same color.
  • 3+ tiles of the same number, different colors.
• Intersections: A tile contributes to multiple sets

Game Phases

1. Setup Phase

• $s$ blocks will be randomly placed onto the map as a part of the map. They can not be moved
• Players alternate drafting tiles from a shuffled pool until racks are full (default: 14 tiles).
• Wildcards are included in the draft.

2. Gameplay Phase

Players place tiles on the grid to score points.

Turn option

1. Draw: draw 1 tile and loose 1 pt
2. Place\Move:
   • Move and Place 1 or more tiles, as long as the end result contains only valid set
   • tile placed may not be in multiple sets with the exception for intersections.
   • The number used by the opponent last turn may not be used
   • If the number of intersection increased, gain 2 pts, else 1

Endgame

• Game ends when no moves remain and the tile pool is empty (or after a fixed number of turns).
• Winner: Player with the highest score. Ties resolved by most intersections.

Testing rules

• Any set of blocks that connect in the board must obey the patterns [asc, dsc, rep, alone] of size at least 3

• Can't place the same number as the opponent in the previous turn.

• Can't place block connecting to the same blocks as the previous turn.

• [Opt] Can't place block connecting to the same block placed by the opponent in the last turn.

• Score: +1 if not connected, +2 if block connects
