A game to play Japanese chess (Shogi) in a browser. Supports AI opponent mode and online multiplayer, and is the second most popular board game in Japan after Go.

A physics simulation game where you adjust fuel, thrust, and launch angle to put a rocket into target orbit. Simplifies real space physics and can be used for educational purposes.

A project to implement 4-player Japanese Mahjong. Accurately implementing the complex win conditions, yaku calculations, and scoring system in code is itself a challenge.

An idle game where you grow virtual plants through simple actions like watering and sunbathing. Real time is reflected in the game, creating a structure that makes you log in every day.

A game where you battle an AI in Korean word chaining. The AI responds by selecting optimal words based on a dictionary DB, and online multiplayer is also supported.

A 2D platformer game combining jumps, gravity, moving platforms, and switch-based puzzle elements to open paths. Includes a level editor so the community can share custom stages.

A dungeon game with procedurally generated maps where you start over from scratch when you die. Provides high replayability with different map and item combinations every run.

A Gomoku game on a 15×15 board where the first player to place 5 stones in a row wins. Supports both AI opponent mode (minimax) and online multiplayer mode.

A memory game where you flip two face-down cards at a time to find matching pairs. Adding animations and a timer makes it a polished mini-game.

A Sudoku game where you fill a 9×9 grid with numbers. The core challenge lies in the automatic puzzle generation and solution verification algorithm, making it great for algorithm learning.

A text-based dungeon exploration RPG. Implement combat, item acquisition, and level-up systems to learn the fundamentals of game logic design.

A game where multiple players answer quizzes simultaneously in real time and compete for rankings. You can create a room and invite friends with a code.
