Chess Puzzles
Mate in One
Five hand-picked checkmate puzzles across classic patterns. Select a piece, find the decisive move. Tests spatial reasoning and tactical vision.
Push Your Luck
Risk Card Game
Flip cards to accumulate points. Cash out before you bust. As the deck thins, the bust probability rises — creating mounting tension with every flip.
Reaction Speed
5-Round Test
Wait for green, then click as fast as possible. Five rounds, personal records, skill tier ratings. Deceptively simple — surprisingly hard to master.

Design Principles Behind Each Game
Core Loop First
Every game has a single-sentence loop: flip or bail, click on green, find the mate. Complexity is layered on top — never substituted for the core.
Transparent Risk
Players always know the current bust percentage, their tier, or how many moves they've tried. Clarity builds trust and keeps frustration low.
Variable Reward
Card values vary (+10, +15, +25, +50), reaction tier labels change, puzzle difficulty scales. Variable rewards are the engine of engagement.
Personal Records
LocalStorage best scores turn a single session into a self-improvement game. The number to beat is your own, which means infinite replay value.
What Each Game Demonstrates
Chess Puzzles
Reveals the player's strategic depth and highlights the satisfaction loop of a single decisive insight.
Push Your Luck
Demonstrates push-your-luck mechanics, dynamic risk curves, and the "just one more" engagement hook central to idle and card games.
Reaction Speed
Shows how a minimalist feedback loop — time, tier, personal best — creates compulsive replayability through transparent skill progression.
