How to Play Mancala
Mancala on Vibe Arcade is a digital version of Kalah, the most widely played form of mancala in the Western world. The carved wooden board shows two rows of six pits plus a large store oval on each end. You control the bottom row; the top row belongs to the computer, or to a second person sitting beside you if you pick the two-player mode described below. Every pit starts with four river stones. On your turn, click any of your six pits that still hold stones. All the stones in that pit are picked up and distributed one per pit, moving clockwise — rightward along your row, then into your store on the right, then leftward along the AI's top row, and so on. Your goal is to fill your store faster than the AI fills its own.
Two special rules shape the strategy. If the very last stone you sow lands in your store, you get a free bonus turn immediately — chain several of these in a row and you can build a commanding lead. If the last stone lands in an empty pit on your own side and the pit directly opposite on the AI's row contains at least one stone, you capture: you take both the just-landed stone and every stone in the opposite pit and add them all to your store in one go. Captures can swing the game dramatically, so planning your sows to set them up is the heart of mancala strategy.
The game ends when either player's six pits are completely empty at the start of their turn. The other player immediately sweeps all remaining stones on their side into their own store. Whoever has more stones in their store wins.
Two-Player Pass-and-Play
Mancala is at heart a two-person game played across a board, so the start menu offers an Opponent choice: vs Computer or 2 Players. Pick 2 Players and the top row stops being the AI and becomes a second human — Player 1 sits with the bottom six pits and the amber store on the right, Player 2 takes the top six pits and the teal store on the left. Both players share one device; nothing is hidden, because mancala is a perfect-information game where every stone is visible to both sides at all times. There is no hand-off screen to click through and no secret setup phase — you simply pass the mouse, trackpad or tablet across after each turn.
The board tells you whose turn it is in four places at once, which matters when two people are looking at the same screen. All six pits belonging to the side on the clock glow in that player's colour, a lit nameplate runs along that player's own edge of the board, the carved plaque in the centre reads PLAYER 1 TURN or PLAYER 2 TURN, and the status line under the board names the player and the row they should be clicking. The moment the turn changes, a ring flares outward from the newly active pits — including on a bonus turn, when play stays with the same player and a pair is most likely to hand over by mistake. A dashed marker also stays on the pit your opponent just emptied and the pit their last stone landed in, so you can see what they did without having to reconstruct it from memory.
On a phone, tap the full-screen button in the top right of the board — the ⛶ icon immediately left of the sound toggle — before you start. It strips away the page title, the navigation and everything else competing for the display, so the board expands into the whole screen — the difference between two people squinting at a strip in the middle of a page and two people playing across a board. Turn the phone sideways as well: the board is wider than it is tall, so landscape gives you around four times the playing area that portrait does, and a phone lying flat between two players in landscape is about as close to a real mancala board as a handset gets. Tap the button again or press Escape to return to the page.
Every rule is identical in both modes — same clockwise sowing, same bonus turn for finishing in your own store, same capture-by-enclosure, same end-of-game sweep — and bonus turns chain for either player exactly as they do against the computer. Keyboard play works for both sides too: the number keys 1 to 6 always select your own pits in sowing order, counting away from you towards your own store, so Player 2's pit 1 is the top-right pit, the one furthest from the teal store, and pit 6 is the top-left pit right beside it. The only things that change are the ones that have to. Difficulty and the Daily Challenge are hidden, because there is no AI in the game to be easy or hard. And a local two-player result is deliberately kept out of your personal best, your win/loss record, your win streak and the online leaderboard: two people sharing one keyboard can hand either side all forty-eight stones in under a minute, so those numbers would stop meaning anything. The end-of-game panel says so plainly rather than leaving you to wonder why a forty-stone win did not register.
Strategy Tips
- Count before you click. Count the stones in a pit to predict where the last stone will land. If it ends in your store, you get a bonus turn; if it ends in an empty own pit with a full opposite pit, it's a capture. Both outcomes are worth planning for.
- Set up capture chains. Leave an empty pit on your side with a full opposite pit, then manoeuvre a future sow to land there. Opponents rarely protect against captures two moves out.
- Know which way the sweep runs before you end the game. When either side empties, every stone left on a row goes into that row's own store — so emptying your own pits hands the AI everything still sitting on its side. If you are ahead, the finish worth playing for is a capture that clears the AI's last occupied pit: the game ends and your remaining stones sweep into your store. If you're behind, keep stones on the AI's side to extend play and hunt captures.
- Prefer moves that grant bonus turns. A bonus turn is a free action. Medium and Hard AI prioritise these heavily — matching that priority is the biggest step up from Easy play.
- On Hard, think two moves ahead. The Hard AI uses minimax to evaluate your best response, so naive greedy play will be punished. Look for moves that are good both now and after the AI's reply.
What Makes This Mancala Different
Mancala is one of the oldest board games in recorded history — archaeologists have found pit-and-stone game boards in ancient Egypt, Ethiopia, and across sub-Saharan Africa dating back over a thousand years. Unlike Chess or Go, mancala was designed to be played with whatever was at hand — seeds, pebbles, shells — on boards carved into stone, wood, or simply scratched in the ground. This version captures that tactile tradition with a canvas-rendered carved-driftwood aesthetic: warm walnut tones, smooth oval pits with worn grooves, and round river pebbles in amber (your stones) and teal (AI stones) against a linen background.
The Kalah rule set this game uses was codified in the 1940s and is distinct from regional variants like Oware (West Africa), Bao (East Africa), and Congkak (Southeast Asia) in its inclusion of the capture-by-enclosure rule and the bonus-turn-on-store mechanic. These two additions give Kalah a richer tactical depth than pure count-and-distribute variants while keeping it approachable in a single sitting. The three AI difficulty levels — random, greedy, and two-ply minimax — let newcomers enjoy the game's flow before stepping up to opponents who genuinely plan ahead.
Frequently Asked Questions
How does sowing work in Mancala?
Click any of your six pits on the bottom row to pick up all the stones in that pit. Stones are then distributed one at a time clockwise — into the next pit, then the next, and so on. Stones pass through your own store (counting it) but skip the AI's store. Click is all the control you need; no dragging or special moves.
What is a capture in Mancala?
A capture happens when the very last stone you sow lands in one of your own empty pits AND the pit directly opposite on the AI's side contains at least one stone. When that condition is met, you take both groups — the just-landed stone and all the stones in the opposite pit — and add them straight to your store in one move.
What gives you a bonus turn in Mancala?
If the last stone of your sow lands exactly in your store — the large oval on the right side of the board — you immediately get another turn. You can chain multiple bonus turns in a single move sequence if you time your pit selection right. The AI gets the same rule: if its last stone lands in the AI store (left oval), it plays again.
What are the three AI difficulty levels in Mancala?
Easy AI picks a random valid pit each turn — great for first-time players learning the rules. Medium AI plays greedily, preferring moves that add the most stones to its store and chasing bonus turns aggressively. Hard AI uses two-ply minimax, evaluating your best response to every move it considers — it avoids obviously bad pits and looks for captures and bonus-turn chains a move ahead.
How is the score calculated in Mancala?
Your score is the number of stones in your store when the game ends. The starting layout gives each player 24 stones (four per pit across six pits), so the maximum possible score is 48 — capturing every stone on the board. Scores from games you win against the AI are eligible for the leaderboard, and your personal best is stored locally so you can see it every time you return.
Can two people play Mancala on the same device?
Yes. Choose 2 Players under Opponent on the start menu and the top row becomes a second human instead of the AI. Player 1 takes the bottom six pits and the amber store on the right; Player 2 takes the top six pits and the teal store on the left. You share one screen and pass the mouse or tablet after each turn — there is no hand-off screen because mancala is a perfect-information game with nothing to hide. The centre plaque, the lit pit rings and the status line all name the player whose turn it is. Every rule is unchanged, including bonus turns and captures for both sides.
Do two-player games count towards the leaderboard?
No, and that is deliberate. A local two-player game writes nothing to your personal best, your win/loss record, your win streak or the online leaderboard, and it cannot complete the Daily Challenge. Two people sharing one keyboard can deliberately feed either side all forty-eight stones in well under a minute, so counting those results would make every one of those numbers meaningless. The end-of-game panel states this outright. The game still counts as a play, and difficulty and the Daily Challenge are hidden in two-player mode because there is no AI in the game for them to configure.
How does the game end in Mancala?
The game ends as soon as one player's six pits are all empty at the start of a turn. The other player then sweeps every remaining stone on their own side into their store. The player with more stones in their store wins. A tie is possible if both end with 24 stones each, though it is rare at higher difficulty levels.
Does Mancala work on mobile and tablets?
Yes. The mancala board scales responsively from phone to desktop using CSS aspect-ratio. Pits respond to tap via touchstart events — no install or app store required, and a tablet flat on a table is a good way to play the two-player mode. There is also a full-screen button in the top right of the board, immediately left of the sound toggle: tap it and the page title, navigation and everything else around the board disappear so the board fills the whole display, which is what you want when two people are sitting either side of one phone. On Android and on desktop the browser bars go too. On iPhone, Safari does not let any website hide its own bars, so the button clears the page furniture and the board grows into that space instead. Tap the same button again, or press Escape, to come back. Turn the phone sideways first — the board is wider than it is tall, so landscape gives you roughly four times the playing area. Keyboard players can press 1–6 to select their own pits in sowing order, which runs left to right along the bottom row and right to left along the top one. The canvas renders crisply on retina screens and stays playable on viewports as narrow as 320 px.
