Logic and memory puzzles on a chessboard. No chess expertise needed.
A new playground for your mind. Exercise your visual memory, attention and reasoning with fun challenges that invite you to recall details, recognize patterns and plan solutions. You do not need to be a chess expert: Silicio brings together logic games, visual memory puzzles and brain teasers for puzzle lovers, beginners and chess players looking for a different kind of challenge. Give your puzzle break a fresh twist. If you enjoy sudoku, word searches or other puzzles, discover a fresh way to give your mind a workout: remember pieces as they vanish, find paths and solve challenges on a chessboard. Start with the easier puzzles and progress at your own pace. Interactive guides explain the goal of each game with a hands-on example you can try on the board. You do not need to know chess openings or tournament strategies to enjoy getting started. SEVEN WAYS TO PUT YOUR MIND IN PLAY • Vanishing Memory: study a real position, remember the pieces that disappear and mark their squares. Progress until you can recall the whole board. • Knight Routes: solve a pathfinding puzzle with L-shaped moves and spatial planning. • Peaceful Queens: place pieces so they do not attack one another and discover how the constraints fit together. • Total Coverage: combine pieces to cover the board using logic and observation. • Knight Exchange: guide the knights to their destinations and plan the order of your moves. • Labyrinths: find a path through obstacles. • Capture Chain: control both colors and capture opposite-color pieces until only one piece remains on the entire board. No alternating turns and no king captures. BRAIN TEASERS AT YOUR OWN PACE Take a break with a mental challenge or continue a saved puzzle. Tap or drag pieces in the logic games. Use hints, undo moves and consult solutions whenever you need them. Interactive help lets you practice before returning to your challenge. WHAT YOU CAN PLAY FOR FREE Includes 58 permanent free challenges across all seven games, plus one rotating free daily challenge. Guides, hints, retries, saving and progress are included.
