Game Modes
CLASSIC: The traditional game mode, much more difficult. Clue positions do not correspond to peg positions. You must guess which peg each clue refers to; therefore, clue positions are random.
INITIATION: Clue positions match peg positions. The clue for the first position corresponds to the peg in the first position, and so on.

Game Types
● Mini 4: 4-peg secret code.
● Super 5: 5-peg secret code.
● Mega 6: 6-peg secret code.
● Giant 7: 7-peg secret code.
● Colossus 8: 8-peg secret code.
● Titan 9: 9-peg secret code.

Layout (left to right)
• Top Row: Settings access, shield action buttons, red shield hiding the secret code.
• Column 1: Records.
• Column 2: Numerical sequence establishing the order of play.
• Column 3: Clues.
• Column 4: Game board.
• Column 5: Pegs in play.

How to play?
• Pegs must be placed in the desired position of the active row.
• Rows are filled consecutively from first to last. Order cannot be changed. When a row is full, it locks and moves to the next row.
• Once the active row is completed, clues appear.
• If you open the shield to see the code before finishing, you can continue playing but the game won't count for records.
• The game ends when the code is guessed or the last row is filled.
• Auto save and load.

Movement types
• Drag and drop.
• Tap the desired color, then tap the target position.

What do clues indicate?
● Black: A correct peg is in the correct position.
● White: A correct peg is in the wrong position.
● Empty: The peg does not exist in the secret code.

Active Row (highlighted)
• Remove a Peg: Drag and drop it outside the row.
• Move a Peg: Drag and drop it to the desired position.
• Place Pegs: Select from the side column or any row containing pegs.

Fix a peg
• Long press a peg in the active row to place it in the same position in all rows above. Long press again to remove the fixed column.

Records
• The first column marks the lowest row achieved for solving the game.
• Different records exist for each combination of game type, level, and options.
• Records can only be cleared at the start of a game, before the first row is completed.
• To clear a record, drag the mark out of its position.

Options
• Play with numbers, colors, letters, geometric shapes, animals, or emoticons
• Autocomplete (Initiation): If a peg is correct, it appears automatically in the next row
• Auto-check: Combination is verified automatically when a row is full. If disabled, a manual button appears
• Repeated colors: The secret code may contain duplicates
• Extra color: Increases the difficulty
• Zoom: The active row appears enlarged. Press the number and drag to move

What’s new

🧩 Mastermind-style logic game (classic board game logic puzzle):

• Classic Mode: The position of each clue does not correspond to the position of each peg. You have to guess which peg each clue belongs to; therefore, the position of each clue is randomized.
• Initiation Mode: The position of the clues corresponds directly to the position of the pegs.

• Fix a color across all rows:
Long-press a peg on the active row. If pressed again, it will be cleared.
