Synonym Switch

Synonym Switch is a standalone HTML5 browser game built for purposeful vocabulary practice and short repeatable challenges. Its core activity is read a target word and choose its closest synonym from four options. Each level offers four distinct vocabulary questions and a completion score. The game includes 20 different levels, each presenting a real task rather than a static informational slide. Players receive immediate feedback when they make a mistake and a clear completion state when they finish the objective.

Designed to be accessible from a computer, tablet or modern mobile browser, the application uses plain HTML, CSS and JavaScript. There is no requirement to create an account, purchase subscriptions, install plug-ins or connect to an external server. All challenge data is included inside the product package, allowing normal play without network access.

The interface includes a welcome screen, challenge selector, visible session timer, instructions, restart, pause, menu navigation and optional sound feedback. Completion records can be remembered using local browser storage. A purchaser can customize colors, wording and challenge data using the included source code, subject to the supplied license.

This collection is suitable for word-game enthusiasts, educational practice, informal family learning, and developers exploring browser-native game structures. It is not an examination qualification, a comprehensive English dictionary or a native Android or iOS application.
