No Ads, No Subscriptions, No Tracking.

Odin's Reversi is the classic game of turning the tables, played with Viking shields. One move can change the whole board, so no lead is safe until the last shield is down.

One price, the whole game. No in-app purchases, no third-party ads, and no tracking.

PLAY TOGETHER, YOUR WAY

Live online: challenge a friend and trade moves in real time. Turn-based online: play at your own pace without being online together. Nearby: connect device to device and play without a Game Center account. Pass & Play: share one screen and take turns. In a live or nearby rematch the sides swap, so nobody keeps the first move. Online matches use Game Center. Turn notifications and a Home Screen widget show when you have moves waiting, and Siri can continue your game.

OPTIMIZED FOR IPHONE DUO

Open the phone and the board fills the inner display; close it and your game carries on, on the outer display, right where you were.

THREE BOARDS, ONE RULE

Place a shield so that a straight line of your opponent's shields — across, down, or on a diagonal — is closed at both ends by yours, and the whole line turns. If you can't place, you pass; when neither side can, the side with more shields wins.

Quick: six by six, a short game for the youngest players. Classic: eight by eight, the board the whole world plays. Grand: ten by ten, with room for long plans and corners worth fighting for.

SIX HOUSE RULES

Runestones: a few runestones are set on the board before play. Nothing lands on them, and no line runs through them. World Serpent: the edges join, as the serpent circles the world, so lines wrap around and there are no corners. Loki's Game: the fewest shields wins. Norns' Opening: every game starts from a dealt, balanced opening. Odin's Favor: give one side up to four corners before the first move. Victorian Rules: the 1880s rules, with an empty center and a limited supply of shields. They work in every mode, and a turn-based or nearby invitation names them before your friend accepts — the only way Odin's Favor reaches another device.

VIKING SHIELDS THAT TURN

Every piece is a Viking round shield, light on one face and dark on the other, and every shield carries its own design: ravens, wolves, dragons, longships and more. Pick a look in Settings: painted, realistic, Viking art, basic, or rune coins. Then choose your board: green leather, oak and iron, or engraved cherry.

FIND YOUR CHALLENGE

Play solo against four computer strengths: Easy, Medium, Hard, and Expert. The coach rings the move it would make and says when it leaves your opponent no move or hands them a corner. Undo lets you try again in local play, and the Video Instructions and How to Play teach every board.
