Mancala is the oldest game on this site by more than a thousand years, and the version almost everyone learns first is Kalah: two rows of six pits, four stones in each, a store at either end, and a rule set that fits on an index card. It is also a game where the first player, playing perfectly, always wins, which tells you two things at once. Every position has a right answer, and most people are not finding it. This guide is about the three ideas that decide almost every game: the exact-landing extra turn, the capture, and the count that tells you when the board is about to end.
How does Mancala work?
The board has twelve small pits, six on your side and six on your opponent's, and two large stores, yours on your right. Each small pit starts with four stones, forty-eight in all. On your turn you pick up every stone from one of your own pits and sow them one at a time into the pits that follow, moving counter-clockwise: along your own row, into your store, then along your opponent's row, skipping their store if you get that far. Two things can happen with the last stone. If it lands in your store, you take another turn. If it lands in an empty pit on your side, you capture it together with every stone in the pit directly opposite, and they all go into your store. The game ends when one side of the board is empty; the stones still on the other side go to that side's owner, and the player with more stones in their store wins. Twenty-five is enough.
How to play Mancala (step by step)
- On your first move, play the third pit from your left: its four stones end exactly in your store, and you move again.
- Before every move, look for any pit whose stone count equals its distance to your store; that is a free turn.
- Take free turns first, then look for captures, then think about the move you are actually going to make.
- Check your opponent's exact landings too, and never leave a full pit opposite an empty one they can reach.
- Keep a stone or two in your rightmost pit as an emergency free move.
- When one side is close to empty, count who banks the leftovers, and play to end the game or to keep it going accordingly.
The exact landing is the whole opening
Count the pits between a pit and your store. Your rightmost pit is one step away, the next is two, and the leftmost is six. Whenever a pit holds exactly as many stones as its distance, sowing it drops the last stone in your store and you go again. At the start every pit has four stones, so the pit four steps from your store, the third from your left, is a free move, and it is the standard opening for a reason. After it, no pit lines up exactly, and the real game begins: the players who win at Kalah are the ones who keep manufacturing exact landings, one stone in the rightmost pit, two in the next, chaining two or three extra turns in a row while the other side watches. Our game lets you pick pits with the number keys 1 to 6, counted from your left, which makes the counting habit easier to keep.
Captures, and the trap behind an empty pit
A capture needs three things: an empty pit on your side, the exact count to land your last stone in it, and something worth taking in the pit opposite. The first two are yours to arrange. An empty pit on your side is not a weakness; it is a loaded trap, and the more stones your opponent piles into the pit across from it, the more it pays. So when you have an empty pit, work out which of your pits could end there, and keep that move in reserve until the opposite pit is worth the trip. The reverse is the most common way to lose: sowing a big pit along your row drops the last few stones into your opponent's pits, and if one of them lands somewhere they can reach with an exact landing next turn, you have gift-wrapped a capture. Before every sow, count where your last stone lands and what it sits opposite.
The lap: thirteen stones come home
There are thirteen places a stone can go on one trip round the board: your remaining pits, your store, and your opponent's six pits. So a pit holding thirteen stones sows all the way round and drops its last stone back into the pit it started from, which is now empty. That is a capture of everything opposite, plus the one stone. A pit with fourteen or more keeps going and the arithmetic changes, so thirteen is the magic number to build toward when you are hoarding, and the number to watch for on your opponent's side.
Hoarding, and where it is safe
The other long-term plan is to stop sowing one pit and let it grow. A big pit is a threat your opponent has to keep counting, it makes a huge sowing move late in the game, and it keeps stones on your side, which matters for the ending. The safest place to hoard is your rightmost pit, the one next to your store, because your opponent can only land opposite it after sowing all the way through your row, which takes a big pit of their own and is easy to see coming. The danger is the capture: a hoard in a pit your opponent can land opposite is a hoard you are holding for them. Count their exact landings every turn while you build.
The ending is a counting problem
When either side runs out of stones the game stops, and every stone still on the board goes to the player whose side it is on. That rule rewrites the last ten moves. If most of the stones are on your side, you want the game to end now, so you sow to empty your opponent's row or simply stop feeding it. If they are on your opponent's side, you want to keep playing, which usually means sowing your bigger pits across the board to keep their row alive. Count the stores, count each row, and decide which player the end of the game is working for before you make the move that brings it closer.
Playing the computer
Our Mancala offers a CPU on two settings and a pass-and-play mode for two people at one screen. Easy plays like a beginner who has learned the rules: it takes a free turn if it sees one, then a capture, and otherwise plays a weighted guess. Hard runs a minimax search seven moves deep, so it will find every exact landing and every capture you leave within that horizon, and it hoards free turns the way good players do. Kalah with four stones a pit has been solved as a first-player win, so the Hard CPU going first is genuinely tough; take the second seat when you want to test yourself. Your record against the machine is kept in your browser, and the mode you were playing is remembered for next time.
Where Mancala comes from
Mancala is a family of sowing games played across Africa and the Middle East for at least 1,700 years; the earliest undisputed boards, from Gedera in Israel, date to the second or third century AD, and the name comes from the Arabic naqala, to move. The two-row, six-pit version with a store at each end that most of the world knows is Kalah, which William Julius Champion Jr. patented and sold in the United States in 1955. Oware, Bao and the dozens of other regional games share the sowing but not the stores or the capture rules, so if you learned Mancala from a grandparent it may not be quite this game.
Frequently asked questions
Is this Mancala the Kalah or the Oware version?
Kalah: six pits a side, two stores, an extra turn when your last stone lands in your store and a capture when it lands in an empty pit on your side. Oware has no stores and captures on counts of two and three instead.
How many stones are there in Mancala?
Forty-eight, four in each of the twelve small pits at the start and none in the stores. The game ends when one side of the board is empty, and twenty-five stones in your store is a guaranteed win.
Does the first player always win Mancala?
With perfect play, yes: four-stone Kalah has been solved as a first-player win. Nobody plays perfectly, so in practice the second player wins plenty of games, and the opening extra turn is the first player's only built-in edge.
If the counting appeals, the checkers guide is about a game where forced moves do the same work that exact landings do here, and our tour of the classic board games puts Mancala next to backgammon, reversi and chess. All of them live on the 2-player shelf.
