CardNova

CardNova is a portrait card puzzle built around observation, planning, and satisfying scan reveals. Study the board while it is visible, then move hidden cards by dragging one card onto another cell. When you are ready, spend a SCAN to reveal the full board and score horizontal or vertical matching lines. Every move matters. Matches score only during scan reveals, so success depends on remembering the hidden layout and choosing the right moment to validate your plan. Cleared cards refill in place, special reward cards appear in later levels, and each completed stage saves your best star result locally. Features: 50 offline single-player levels. Increasing board sizes from compact 3x3 layouts to taller 4x6 challenges. Bright card themes, special score/move/scan reward cards, and clear result feedback. Local progress, level select, star ratings, background music, and a music toggle. Built with SpriteKit and Objective-C, targeting iOS 13 and later with portrait layouts adapted for iOS 13-supported iPhone and iPad devices. CardNova does not require online gameplay accounts or cloud saves.
