About this game

A notebook. Two castles. One gloriously ridiculous siege.

Doodlekeep: Knights of the Margin is a single-player strategy game drawn in pen, pencil, and a little colored ink. Recruit your company, build a balanced army, and watch tiny warriors march into battle. Your orders decide who holds the page.

START WITH CHAPTER I
Play the first chapter and its three battles free. A single Full Notebook purchase unlocks the remaining eight chapters and Endless Siege. Pay once. No ads. No subscriptions. Your progress carries on when you unlock.

A NOTEBOOK FULL OF ADVENTURE
The full game contains 27 battles across nine chapters, from castle margins and frozen lands to desert ruins, lava fields, and kingdoms in the sky. Each chapter brings different battle boards and a powerful guardian.

BUILD YOUR COMPANY
Command nine unit types, including shield knights, longbows, ink wizards, mounted paladins, catapults, ballistas, and fire-breathing page drakes. Upgrade equipment and armor in the Armory, strengthen your castle defenses, and hire three distinctive heroes at the Tavern.

SMALL KNIGHTS, BIG PERSONALITIES
Enjoy sketch-style sword swings, arrows, magic, crumbling castles, and drawn flames. Rival castle lords argue from their windows while tiny warriors answer with exuberant wordless battle cries. Medieval music and battle sounds complete the notebook world.

KEEP TURNING THE PAGES
Replay battles for stars, earn crowns through play, and see how long your company can survive Endless Siege with the Full Notebook. Save progress locally and export a chronicle backup to keep it safe.

PLAY OFFLINE
The installed game includes its artwork, music, sound effects, and campaign. Chapter I works offline, and purchased chapters remain playable offline after the unlock is verified on your device. Internet is needed to purchase or restore the Full Notebook, or to download updates. Restore with the same Google Play account after reinstalling or changing devices. No separate game account is required. Store purchases do not transfer between platforms.

New chapters and battlefields coming soon!
