Spectrum Shift

Game Objective
Place hexagonal tower blocks of different colors and heights on a hexagonal grid board. Clear a specified number of hexagons to pass the level, while avoiding failure by filling up the board.

Basic Rules

Game Area

Main Board: A large grid composed of multiple regular hexagonal cells

Selection Area: Three optional hexagonal tower blocks displayed below the board

Target Area: Shows the required number of hexagons to clear for the current level on the side of the screen

Tower Block Composition
Each tower block contains:

A random number of stacked hexagons

Each hexagon has an independent color (red, yellow, blue, green, purple, etc.)

The shape of the tower block is fixed and cannot be split or rotated

Placement Rules

Select one tower block from the three below to place on the board

The tower block must be completely placed on empty cells

Color Stacking Mechanism

Same-Color Adjacency: When a hexagon in the tower block touches an adjacent hexagon of the same color on the board

Upward Stacking: The touching same-color hexagon "flips" and stacks onto the new tower block

Height Accumulation: Stacking increases the height of the hexagonal tower at that position

Clear Condition

When a hexagonal tower at a certain position reaches a specific height

Cleared hexagons are counted toward the level target

Failure Condition

There is insufficient empty space on the board to place any of the optional tower blocks
