A kingdom has spilled into the margins. Raise the blue banner and lead a company of doodle knights through a medieval adventure illustrated in loose pen and ink, irregular crosshatching, and restrained coloured-pencil accents. COMMAND YOUR COMPANY Recruit shield knights, swordsmen, pikemen, longbow archers, wizards, mounted paladins, siege engines, and dragons. Spend ink carefully, choose your moment to rally, and break the opposing keep across 27 campaign battles in nine chapters. BUILD A STRONGER KEEP Visit the Royal Armory to improve your equipment, strengthen your castle defenses, and stop at the tavern to recruit heroes. Your choices shape the company you send back into battle. OPEN THE SIEGE PAGES Take aim at 30 castles with catapults, ballistae, and trebuchets. Adjust angle and power, choose ammunition with different effects, and bring the walls down while protecting the blue knight. RIDE INTO THE JOUST Challenge champions across nine chapter cups. Time your charge, aim your lance, and brace for impact. Improve your equipment in Armory & Stables and return to challenge riders again. ASK OSRIC. HE WILL ANSWER LOUDLY.

Verdict

The call

The clearest difference is ads: Doodlekeep at none against Tengai Saga's shown. Doodlekeep also leads on update cadence (every 5 days vs every 3 months). Tengai Saga's advantage is iOS requirement (12.0 vs 15.0). On price, in-app purchases and device support there is nothing between them.
