About

Enjoy a unique new interpretation of Edgar Rice Burroughs’ century-old game Jetan. This software runs on iPhone, iPad, and even Mac. Complete with Burroughs-authentic design, new animations and sound effects for the various pieces, with its own new musical score. Play with a friend or vs the computer in this special variant of chess, fully configurable with difficulty and rules settings. Play under the rules of Manator, where squares must be won in combat, determined by odds weighted by prowess and momentum. Give the automated opponent different personalities, choosing between the noble fool and the depraved coward, as well as draw tendency. Let the music loop or advance by game milestones. Disable or turn down the music, animations, and sound effects. Show or hide the next available moves. Preview the movesets of the pieces before you play, read and alter the rules, and more.

What's New in Jetan

1.0.1

November 11, 2026

WHAT'S NEW 1. The Chief's check, shown on the board The app already marked a threatened Princess with a red square. It now marks a threatened Chief too. Its square turns blue when lesser pieces threaten it and green when the opposing Chief does, and each threat has its own sound. A threatened Chief or Princess keeps its color for as long as the threat stands, on either player's turn, so a danger left on the board stays in sight. 2. A sound fix If a sound was triggered while the sound effects were still loading, the effects could be lost. They now load reliably. 3. The title page on iPad and smaller iPhones On an iPhones and iPads with shorter screens, the planet on the title page could crowd the title and the menu. It now gives up size so that everything has room. 4. Smoother animation The planet behind the title page and the transition into the demonstration game are now drawn by GPU shaders instead of stacked image layers. They look the same as before but run several times faster on older devices: on a 6th-generation iPad the transition went from about 100 ms a frame to about 30. 5. Finishing touches The crowd sound in the Manator variant now loops without a seam, and a stray shadow along the top edge of Phobos, the moon orbiting Barsoom (Mars), has been removed.
