Jocker Rotation

ONE JOKER, ONE RING OF CARDS Eight to twelve cards are arranged in a circle. The Joker sits at the center, pointing at one sector. Rotate the Joker to aim at a card, then activate its effect. The card transforms — its suit cycles, its color flips, its rank shifts, or it swaps with the opposite card. Your goal is to transform the ring until every card matches the target pattern. AIM AND ACTIVATE Drag or tap to rotate the Joker. Rotation itself does not count as a move. Press Activate to apply the effect to the selected sector — that counts. Each level gives you one or two effects to work with. Plan your sequence carefully, because fewer moves earns a higher star rating. SIX EFFECT TYPES Suit Shift cycles a card through the four suits. Color Flip swaps red and black. Rank Shift moves a card up or down in value with wrap-around. Opposite Swap exchanges a card with the one directly across the ring. Neighbor Flip transforms the two cards adjacent to your target without touching the target itself. Mirror applies an effect to both the selected card and its opposite simultaneously. 48 HAND-CRAFTED LEVELS Six chapters introduce effects one at a time, then combine them. Suit Rotation teaches the basics with eight cards and a single effect. Color Rotation adds independent color logic. Rank Rotation introduces value shifting. Mirror Pair and Opposite Swap bring spatial planning. Mixed Rotation combines two familiar effects in twelve-card puzzles. Every level is authored, validated for solvability, and has a fixed optimal move count. STAR RATING Three stars for solving at or below the optimal move count. Two stars within two extra moves. One star for anything beyond that. Passing is never blocked by move count — you can always complete the level and replay later to improve. UNDO AND RESTART Undo steps back one move at a time through the full session history. Restart resets the board to its original state and clears the move counter. Both are available at any point during a puzzle. TARGET OVERLAY Tap the Target button at any time to see the goal pattern without losing your current progress. On easier levels, a permanent thumbnail stays visible throughout. RESUME AND REPLAY Close the app mid-puzzle and your exact board state is saved. Reopen and continue from the last move. Completed levels track your best move count and can be replayed any time to chase a better rating.
