Built two browser puzzle games

Original: I Built 2 Browser Puzzle Games from Scratch A deep-dive into building Color Sort Puzzle and Block Blast

Short summary

The author built two browser-based puzzle games—Color Sort (liquid sorting) and Block Blast (Tetris-style placement)—using React and CSS without game engines. Technical highlights include solvable-level validation logic, a 3×3 proximity search for crowded mobile boards, Web Audio API sound synthesis (zero audio files), and non-passive touch listeners to freeze scrolling during gameplay. Both games are live at 7x.games as part of a 150+ original game project.
