RGB+ offers a unique twist on the classic sliding block puzzle concept by incorporating the additive RGB Color Model into its gameplay. Players must swipe in various directions to move color circles around the grid, combining primary colors to create secondary colors and ultimately aiming to clear the grid by strategically matching circles. The game introduces Red, Green, and Blue circles after each swipe, challenging players to think strategically to maximize their scores.

With a minimalist design and fresh theme, RGB+ provides a visually appealing and engaging experience for puzzle enthusiasts. The game features familiar sliding block mechanics while offering a new challenge with its color-mixing concept. Additionally, players can compete with others on the leaderboard and share their high scores, adding a competitive edge to the gameplay.
