Clue Formula is a 3D Mahjong puzzle with IQ-test style tiles and pattern-matching challenges. Your goal is to complete all levels. In each level, remove all tiles by selecting matching pairs. Not every matching tile can be selected. A tile is selectable only when it is positioned at the end of a row - when there is no neighboring tile on at least one side (left or right) within the same layer. To complete a level, you need to find matching pairs where both tiles are selectable. Each new level becomes more challenging as you advance. A hint can show all selectable matching pairs. A shuffle can rearrange the remaining tiles and help you continue the level. Key Features: 3D Mahjong Puzzle: Match selectable pairs and clear each level. IQ-Test Style Tiles: Match tiles using shapes and symbols. Layered 3D Levels: Look through rows and layers to find selectable matching pairs. Leaderboards: Complete levels and compete for a place on the leaderboards. Accessibility and Device Support: Clue Formula is fully playable with VoiceOver. Clue Formula is fully supported on Mac. Extra hints and extra shuffles are available for purchase.
