Cybergames is a daily puzzle game themed around cybersecurity and IT, described as Wordle meets cybersecurity. Each day offers six puzzles that are the same for all players: a Wordle-style passcode, a mini crossword, a hexdump to decode, a traceroute to follow, a log to grep and a lock to brute force. Daily puzzles follow a topic (for example digital forensics), and a rubber duck character provides hints. In addition to the dailies, there are 15 themed tracks (networking, cloud, AI, forensics and others) with 50 levels each, for a total of 7,500 puzzles. No ads and no account are needed to play; signing in is optional and only syncs your streak between the website and the mobile apps. It is made by a solo developer and is free to play. Available on the web in the browser, and also as iOS and Android apps.
