Word Unknown takes inspiration from both hangman and mastermind to create an incredibly fun and simple word game experience. Your objective is to guess a randomly generated word in as few moves as possible using both lexical and deductive logic. Once a legal guess is made, you'll get X's and O's in response. Each X represents a correct letter in the correct position, and each O represents a correct letter in the wrong position. There are five different difficulties (word lengths) to choose from and a daily challenge for each so you can compete with friends! Best of all, the game is 100% free and open source! Word Unknown is the second word game developed by Christopher Cinq-Mars Jarvis. His first is Synonymy, narrated by Richard Dawkins, which received distinctions at GDC and E3.

ACCESSIBILITY — GO FOR EVERYONE Goban3D makes Go genuinely accessible — across ability, skill level, device, region, and language. No other Go app on the App Store declares any accessibility features. Goban3D has 100% coverage across all seven Apple categories: VoiceOver with full board-position labels, Voice Control, Dynamic Type, Reduce Motion, Reduce Transparency, Sufficient Contrast, and Differentiate Without Color. The app starts in 2D by default, and the 2D SwiftUI board is where the full accessibility stack lives — including complete VoiceOver board navigation. When VoiceOver is on, the 3D toggle is disabled to keep the accessible experience front and centre. A dedicated high-contrast mode and adjustable grid-line thickness help players with low vision. DEVICES • Also runs on Mac and visionOS via "Designed for iPad" • Minimap on smaller iPhones ensures every intersection meets Apple's 44pt minimum tap target, even on 19×19 Free to play, with gameplay that is always ad-free. A brief ad appears on launch and just before scoring mode, so your time on the board is never interrupted. Remove all ads with an optional yearly subscription.

Verdict
The clearest difference is in-app purchases: Word Unknown at none against Goban3D's 1. Word Unknown also leads on ratings volume (11 vs 1) and iOS requirement (6.0 vs 26.0). Goban3D's advantage is update cadence (every 4 days vs every 16 months). On price, rating, ads and device support there is nothing between them.
