About Sedef Checkers
Sedef is mother-of-pearl, the shell set into the walnut boards of coffee houses from Istanbul to Damascus. Every piece here carries a pearl inlay, a star once it is crowned, and the board plays by whichever rules your table grew up with.
Checkers and draughts against the computer in seven rule sets, from English checkers to Turkish dama: three levels, a ten-opponent ladder and puzzles.
How to play Sedef Checkers
On the title screen pick Match, Ladder or Puzzles, then press Play. Every mode starts from the rules card: the board opens in the rule set most players in your language use (English checkers in English, Turkish dama in Turkish, Russian shashki in Russian, Brazilian rules in Portuguese, international 10x10 in French), and one tap on the rules row switches to any of the seven: English, Turkish, international, Brazilian, Russian, Spanish and Italian. Tap a piece to see where it can go and tap the square, or drag it there. A capture over several pieces is played by tapping the last square; when two routes end on the same square, tap the stops on the way. Captures are compulsory in every rule set, and the rules card says which capture must be chosen: any capture, the one that takes the most pieces, or (Spanish and Italian) the most pieces and then the most kings. A man that reaches the far row is crowned; kings fly over any distance except in English and Italian draughts. You win when the computer has no move left, all pieces taken or blocked. Match: choose Light or Dark and Easy, Normal or Hard; Undo takes back your last move and the reply, Hint shows the computer's choice for you. Ladder: ten opponents from Rookie to Master for each rule set, each with its own way of playing; beat one to open the next. Puzzles: four chapters of ten per rule set, win in 1 to 6 moves against the best defence, each with exactly one winning first move; a wrong move is taken back. The daily puzzle is the same for every player. Winning at Normal, beating the third ladder opponent or solving a chapter 2 puzzle opens hard mode: no Undo, no Hint, and one wrong puzzle move ends the puzzle.

Features
Seven rule sets
English checkers, Turkish dama, international, Brazilian, Russian, Spanish and Italian draughts, all on one board. Switch between them with one tap on the rules card, no restart needed.
Three match levels
Easy, Normal and Hard. Hard takes up to 1.5 seconds to answer and plays a noticeably stronger game than Normal.
Ten-opponent ladder
Rookie through Master, each with its own way of playing, one rule set at a time. Beat one opponent to open the next.
280 puzzles
Four chapters of ten puzzles for each of the seven rule sets. Win in 1 to 6 moves against the best defense; a wrong move is taken back automatically.
Daily puzzle
One puzzle shared by every player each day, drawn from the harder chapters of the rule set you have selected.
Hard mode
Unlocked by winning a Normal match, beating the third ladder opponent, or solving a chapter 2 puzzle. Removes Undo and Hint in Match and Ladder; in Puzzles a single wrong move ends the puzzle instead of being reverted.
Tips
- Captures are compulsory in every rule set, so a piece offered on purpose can pull one of the computer's pieces out of line and open a double capture for you.
- Keep your back row filled for as long as you can: a crowned flying king controls whole diagonals, or whole rows and columns in Turkish dama.
- Under the majority rule (international, Brazilian, Turkish and Spanish) count every capture chain before you move, because the longest one must be played by both sides.
- In English and Italian draughts a king steps only one square, so trade pieces when you are ahead and drive the last ones into a corner.
- In a puzzle the side to move always wins: look for the sacrifice that forces the reply you need, not for the capture in front of you.
Frequently asked questions
How do I win a match?
The computer runs out of legal moves, either because every one of its pieces was captured or because the pieces it has left are all blocked.
How many puzzles are there?
40 per rule set (280 across all seven): four chapters of ten, each solvable in 1 to 6 moves against perfect defense. A wrong first move is taken back so you can try again.
Is there a daily puzzle?
Yes, one per day, the same for every player. It is pulled from the later chapters of the puzzle set for whichever rule set you have selected that day.
What does hard mode change?
In Match and Ladder it removes Undo and Hint. In Puzzles it removes Hint and a single wrong move ends the puzzle on the spot instead of being taken back.
Does my progress save?
Yes, on this device only, there is no account. You can move it to another device with a sync code from the menu.
Can I play on a phone?
Yes, the board is built for touch: tap a piece then tap or drag to where it should go.
