Simple Roulette Maker vs Laetus

This app allows you to create a roulette wheel, which is useful for deciding things randomly. You can set the number of items on the roulette and the likelihood of each item being selected (the size of the item) to create your own original roulette. The data of the created roulette can be saved, so you can quickly prepare a roulette for various situations. When you press the button in the center of the roulette, it spins either clockwise or counterclockwise. The spinning speed is random, and the roulette can be stopped by either the passage of time or by tapping the center button again. Please use it like drawing straws when you have trouble deciding something!

Analyze decisions, uncertainty, and personal luck through real-world experiments. Laetus is a research-oriented platform that explores how people make decisions under uncertainty using probability, behavioral analytics, simulations, and long-term observation. Originally built around international lottery simulations, Laetus has evolved into a broader experimental environment where randomness becomes a measurable dataset rather than a source of gambling. No real-money gambling. No ticket sales. No financial risk. WHAT YOU CAN DO • Generate combinations using tap, drawing, symbols, or structured selection • Explore 60+ international lottery formats and their statistical characteristics • Track your personal Luck Index and long-term behavioral trends • Monitor Luck Pulse to record perceived luck over time • Analyze historical performance using probability, ROI, budget, and behavioral statistics • Explore Bitcoin nonce experiments and additional randomness datasets • Receive personalized analytical insights and decision-support recommendations • Export reports and review detailed visualizations of your activity LAETUS 2.0 Laetus 2.0 expands the platform beyond lottery analytics. The new generation introduces: • Decision-support tools based on behavioral observations • Flexible Home Experience profiles • Expanded personal insights and forecasting • Bitcoin-based randomness experiments • Improved community statistics • Smarter recommendations • Enhanced historical analytics • Faster backend processing and improved data quality BEHAVIORAL ANALYTICS Laetus studies not only outcomes but also how decisions are made. Examples include: • Random vs structured choices • Distribution and clustering patterns • Selection consistency • Behavioral changes over time • Perceived luck versus measured outcomes RESEARCH PHILOSOPHY Laetus does not attempt to predict the future or guarantee successful decisions. Instead, it helps users explore uncertainty, recognize behavioral patterns, and better understand how randomness interacts with personal decision-making.
