Twenty-seven games. Nothing else asking for attention.

Open any two cards. A matching pair stays face up. Different cards show briefly, then flip back together so the board never shifts.

Choose a card or an ordered stack, then choose where it should go. Empty columns accept kings. The four home piles begin with aces. Choose the draw pile again after it empties to turn the waste pile over. Undo is always available after a move.

You may only ask for a rank already in your hand. If Orbit has it, every card of that rank moves to you and you may ask again. Otherwise you draw one card. Orbit follows the same rules, one visible turn at a time.

Coral moves toward row 1; Lilac moves toward row 8. Choose one of your outlined pieces, then a marked landing square. A jump over the other color is required whenever one is available. Keep jumping with the same piece while another jump is possible. Reach the far edge to become a king that can move in either direction.

Take turns placing X and O. Three matching marks in a row, column, or diagonal win the round. If all nine squares fill without a line, the round is a draw. In computer modes you are X and move first. First open always chooses the lowest-numbered empty square. Line aware tries to win, block, take center, take the first open corner, then take the lowest-numbered open square. Previous and Next treat your move plus its immediate computer reply as one turn.

Coral and Gold take turns choosing columns. Each piece falls to the lowest open space. Connect four pieces horizontally, vertically, or diagonally. A full board without a line is a draw. The other color starts the next round.

Choose a marked square. Your disk must trap one or more of the other color horizontally, vertically, or diagonally. Trapped disks flip to your color. If one player has no legal move, their turn passes automatically. The game ends when neither player can move; the color with more disks wins.

Choose a pit on your side. Drop one stone into each next pit and your own store, skipping the other player’s store. Finish in your store to move again. Finish in an empty pit on your side to capture that stone and every stone directly opposite. When one side is empty, the other side’s stones move into its store; the larger store wins.

First, alternate placing nine pieces each. Three of your pieces on one drawn line form a mill, letting you remove an opposing piece that is not already in a mill—unless every opposing piece is protected. After placing, move one piece to a connected open point. With only three pieces, you may fly to any open point. A player loses with fewer than three pieces or no legal move. Fifty movement turns without a capture end in a draw.

Coral and Lilac take turns choosing one open horizontal or vertical line between neighboring dots. If your line completes one or two boxes, those boxes become yours and you draw again. Otherwise the turn passes. When every box is claimed, the player with more boxes wins. The other color starts the next round.

The number above each column and beside each row is the exact number of ship squares in that line. Choose an unknown square once for ship, again for water, and again to clear it. Given clues have a yellow inset and cannot change. “Fill certain water” marks unknown squares in any row or column whose ship total is already met. Decide every square, then check the fleet.

Choose one of your outlined pieces, then a marked destination. The board will not allow a move that leaves your king in check. A king may castle with an unmoved rook when the spaces are clear and none of the king’s path is attacked. A pawn may capture a just-advanced neighboring pawn en passant, and a pawn reaching the far edge may become a queen, rook, bishop, or knight. Checkmate wins; no legal move without check is stalemate. Undo restores the entire previous move.

Roll, choose an outlined checker stack, then choose a marked destination. A point holding two or more opposing checkers is blocked; landing on one opposing checker sends it to the bar. Checkers on the bar must re-enter before any other checker moves. Use both dice when possible; doubles provide four moves. Once all fifteen checkers are in your final six points, move them off with exact rolls or a larger roll when no checker is farther away. The first player to bear off all fifteen wins.

The yellow tile starts the chain. Choose a domino from the hand; if it can match the number at the left or right end, that end button becomes available. Choose an end and the domino rotates automatically so equal numbers touch. Use every domino to complete the puzzle. Undo removes the last placement, and reset returns the current puzzle to its anchored tile.

Choose one letter as the start, then choose the end of a straight horizontal, vertical, or diagonal line. The line may run forward or backward. If its letters match a word in the list, the whole word stays highlighted. A line that does not match simply clears so you can try again. Undo returns the most recently found word.

Choose any tile directly above, below, left, or right of the open space. That tile slides into the opening. Keep moving neighboring tiles until the numbers read from left to right and top to bottom, with the open space last. Symbol view changes only the tile labels; the same numbered order and puzzle stay in place. Undo, reset, or begin another guaranteed-solvable puzzle whenever you like.

Choose an outlined peg, then a marked empty hole exactly two spaces away. The move must pass over one neighboring peg horizontally or vertically; that middle peg is removed. If a peg has more than one jump, every legal destination is marked. The board ends naturally when no jump remains. Use Move back to review earlier choices without a score or timer.

Choose Start, Middle, or Home to lift that tower’s top disk. Then choose another tower to place it. Empty towers accept any disk; otherwise the moved disk must be smaller than the top disk already there. Move every disk to Home to finish. There is no timer, target move count, grade, or penalty—use Undo whenever you want to reconsider.

Choose four named symbols, then check the guess. “Exact” counts symbols in the correct place. “Elsewhere” counts correct symbols in another place, without counting any symbol twice. Colors reinforce the shapes but are never the only clue. Solve within eight guesses or the hidden code is shown; then reset or choose the next fixed offline code.

In Reveal mode, choose a square to uncover it. A number says how many of its eight neighbors contain mines; a blank opens its connected safe area. In Flag mode, choose a hidden square to add or remove a clearly marked flag. Flags are notes and do not have to be perfect before safe squares can open. The first reveal is relocated if necessary so it can never end the board. Reveal all 54 safe squares to complete the puzzle.

Choose an outlined Coral piece, then a marked diagonal landing square. Captures are required across all three layers. A square marked A, B, C, or D is a portal: entering it finishes the move at its paired endpoint on the neighboring layer, which must be open. If another jump is available there, continue with the same piece. Layer buttons change only the view, never the position or legal moves. Undo restores the whole cross-layer turn.

Coordinates are always announced as layer, row, column. Coral regular pieces advance toward 1,1,1 by moving one cell along a face diagonal—two coordinates change together while the third stays fixed. A jump travels two cells along the same vector over one rival. Kings may use any face-diagonal direction. Layer, Row, and Column views show the same position as different flat slices; changing the view never changes legal moves. Captures are required throughout the cube, and Undo restores the whole turn.

Coordinates always mean layer, row, column. Rooks travel along one axis. Bishops travel along a two-axis face diagonal. Kings move one cell using either pattern. Coral pawns move toward layer 1 and capture one layer forward plus one row or column step. A legal move can never leave the Coral king attacked anywhere in the cube. Choose a piece and destination; promotion requires an explicit Rook or Bishop choice. Slice controls change only the view. Undo restores the complete move.

Timeline A is the original saved history. Its marked Fork state is the only editable board. Choose it, select an outlined Coral piece, then choose a marked final landing to create timeline B. A multi-jump is stored as one complete branch turn, not several history states. Captures remain mandatory, crowning waits until the turn ends, and Undo branch removes B without changing any A state. Pieces never travel between timelines.

Timeline A is immutable saved history. Return to its marked Fork, select a Coral piece, and choose a legal full-cube destination to create B2. Layer, Row, and Column slices only change the view. A branch move is offered only when it leaves the Coral king safe; B2 recalculates check, mate, stalemate, and promotion. Pieces never move between timelines. Undo branch deletes B without changing A.

Coordinates always mean layer, row, column. Rotation changes only the display, never a piece coordinate. Layer, Row, and Column planes are different windows into the same cube. Stations 1–3 ask you to prove that identity and legal moves survive those view changes. Stations 4–5 replay one legal move as immutable Before, Route, and After frames; the Route names its source, destination, and direction before the board changes.
