Daily Pokémon Battle Game

The author created a daily Pokémon battle game as a browser-based strategy puzzle called Daily Red Pokémon. The game presents players with the same six-Pokémon team each local day, with the goal of making meaningful decisions rather than grinding levels or collecting items. The daily constraint ensures that every player faces the same team on any given day, creating tension for failed official battles while allowing unlimited practice attempts.

The game saves player progress in the browser, enabling users to resume unfinished battles later without needing an account or server-side profile. The battle simulator runs in a browser Web Worker, keeping the interface responsive while turns process. Using Gen III battle data and damage rules, the simulator calculates physical and special damage based on move type, with additional factors including weather, status effects, held items, abilities, move PP, switching, and fainted Pokémon.

A simple heuristic is used for the opponent AI, scoring legal moves based on estimated damage, accuracy, type immunity, status effects, recovery, and setup moves. This approach makes the opponent consistent but not perfectly optimal, allowing for interesting mistakes.

The user interface centers around a few repeated actions: choosing a lead Pokémon, inspecting available moves and PP, selecting an action for the current turn, reading the event log, and switching when necessary. Practice sessions don't overwrite the official daily record. The game operates without a backend, keeping hosting simple and relying on Astro's static file generation.

The author learned that visible rules are crucial for player learning from losses and that deterministic content affects balancing. The daily team pool and rules version must be considered part of the product. The game can be tried at https://dailyredpokemon.org/.
