Gameplay Mechanics

Core Mechanics

Unlike a slot's fixed reel grid, 'Rainbow Ball - Power of Light' uses dynamic 3D environments as interactive level geometry. These settings range from 'corridor perspectives with varying stripe widths' to 'dark green misty fog' woodland levels, requiring spatial navigation. The 'grid' is an active landscape, not a static symbol matrix.

Progression System

'Rainbow Ball - Power of Light' doesn't operate on payline or 'ways-to-win' payout systems. Progression ties directly to stage completion, a binary success metric. The main goal: 'roll and float the ball to the goal,' leading to a 'Level completion window' showing '1-1Clear.'

Control Features

Controls are intuitive, 'with just one finger' – ideal for mobile touch-and-drag or tilt input. A bottom 'control panel' offers Quality of Life features:

  • Circular arrow for immediate restarts
  • Two vertical bars for pause
  • Speaker for sound toggle
  • Four arrows from centre for fullscreen
  • Game skip function for accessibility

Special Mechanics

The 'game skip function' is a key accessibility tool, letting players bypass challenging or unwanted stages. This directly enhances user experience and retention, especially for casual players or 'first-time action game players' in the UK. 'Various tricks' refers to the diverse environmental hazards, interactive elements, and physics-based puzzles built into each 3D stage.
