Ciall: Chess, Sudoku & Puzzles

Ciall brings together eight timeless board and puzzle games into a single, cohesive collection designed for deliberate and contemplative thinking. Built from the ground up with a calm aesthetic and respectful interface, Ciall offers deep intellectual engagement without timers or intrusive interruptions.

EIGHT TIMELESS GAMES
• Chess: Play against an adaptive device opponent across three difficulty levels or share the board with a friend in two-player pass-and-play mode. Includes full move validation, check detection, and piece tracking.
• Go (9x9): Experience the ancient game of territory and balance on a focused 9x9 board. Play solo against the device engine or two-player local with automatic Chinese area scoring and territory visualization.
• Sudoku: Solve handcrafted number puzzles ranging from gentle practice to challenging deduction. Features optional pencil notes, mistake indicators, and full move history.
• 2048: Slide tiles and merge numbers toward the 2048 tile and beyond on a clean, responsive 4x4 grid with move undo support.
• Minesweeper: Uncover safe ground using pure logic. Choose between 8x8, 9x9, and 11x11 grid sizes with quick-toggle flagging and misclick safety.
• Memory Match: Uncover matching pairs across multiple grid sizes. Play solo or take turns in two-player mode to see who remembers more pairs.
• Lights Out: Toggle grid cells to turn off every light. Test your spatial reasoning across 3x3, 4x4, and 5x5 configurations with optional step-by-step hints.
• Tic-Tac-Toe: Enjoy quick rounds of tactical placement against smart device AI or a companion on the same screen.

CALM, FOCUSED DESIGN
• No Countdown Pressure: Active games never display ticking countdown timers or score decays. Puzzles are meant to be solved at your own thoughtful pace.
• Undo and Restart: Explore candidate moves freely. Every game supports move retraction and one-tap board reset.
• State Preservation: Your active board and puzzle states remain saved when switching apps or rotating your screen.
• Clear Outcomes: Transparent win, loss, and draw summaries allow you to review your final board configuration before starting your next match.
