Savvy Scratch is a lottery scratch-off companion built for players who want more than blind luck. Instead of just showing what a ticket looked like on launch day, Savvy Scratch helps you see what matters now: which games have gone bad, which ones are still fresh, and where the best remaining jackpot opportunities may be hiding.

Scratch-off odds change over time as prizes get claimed, but most players are left guessing. Savvy Scratch tracks publicly available lottery data and turns it into something useful, helping you quickly spot games that may be worth a closer look and avoid the ones that are already burned up. That means less guesswork, better timing, and a smarter way to play.

The app is designed for everyday scratcher players who want clearer information, not more clutter. Whether you are chasing top prizes, trying to avoid bad games, or just want a faster way to compare tickets before you buy, Savvy Scratch gives you a more informed view of the scratch-off landscape.

Built by professional gambler and advantage player Doug Moeller, Savvy Scratch brings a strategy-first mindset to a type of game most people play without one. The goal is simple: help players make better decisions with better data.

Users can sign up free to see bad games and new games, then upgrade for deeper insights and full access to the platform.

React Engine features and specs

  • Isomorphic rendering
    React Engine enables both server-side and client-side rendering of React components, providing a seamless isomorphic/universal JavaScript experience. This allows for faster initial page loads and better SEO while maintaining rich client-side interactivity.
  • Express.js integration
    React Engine is designed as a view engine for Express.js, making it easy to integrate React into existing Express-based applications with minimal configuration. It follows familiar Express conventions for setting up view engines.
  • Built-in React Router support
    The library comes with built-in support for React Router, enabling developers to easily set up server-side and client-side routing without complex manual configuration.
  • PayPal backing
    React Engine was developed and maintained by PayPal, which provided credibility and ensured it was battle-tested in a large-scale production environment before being open-sourced.
  • Simplified setup
    The library abstracts away much of the complexity involved in setting up server-side rendering with React, reducing boilerplate code and allowing developers to get a universal React application running quickly.

Possible disadvantages of React Engine

  • Abandoned project
    The repository appears to be no longer actively maintained, with no recent commits or updates. This makes it risky to use in production as bugs and security vulnerabilities may go unpatched.
  • Outdated dependencies
    React Engine was built for older versions of React and React Router. It may not be compatible with modern versions of React (16+, 17, 18) or React Router (v5, v6), limiting its usefulness in current projects.
  • Limited ecosystem support
    The library is tightly coupled to Express.js, meaning it cannot be easily used with other Node.js frameworks like Koa, Hapi, or Fastify, reducing its flexibility.
  • Better modern alternatives
    Modern tools like Next.js, Remix, and Vite with SSR plugins provide far more comprehensive and well-maintained solutions for server-side rendering with React, making React Engine largely obsolete.
  • Limited documentation and community
    The project has relatively sparse documentation and a small community, making it difficult for new developers to troubleshoot issues or find examples and best practices for advanced use cases.

Analysis of React Engine

Overall verdict

  • Unable to verify a project specifically named 'React Engine' on GitHub with confidence, as this does not correspond to a widely recognized or well-documented open-source project that I have reliable information about. There may be multiple small or niche repositories using this name, and quality would vary significantly between them.

Why this product is good

  • React Engine is not a commonly recognized name in the mainstream React ecosystem
  • No verifiable consensus data on stars, maintenance status, documentation quality, or community adoption is available
  • Could refer to a personal project, a boilerplate, a rendering engine, or a niche tool - without more context, its quality cannot be assessed
  • Names like this are sometimes used for student projects, abandoned repos, or experimental tools that lack production readiness

Recommended for

  • Not recommended without further verification
  • Developers should search GitHub directly, check star count, last commit date, open issues, and documentation before adopting
  • Best suited for evaluation on a case-by-case basis rather than a blanket recommendation
  • If you have a specific repository URL, sharing it would allow for a more accurate assessment

Questions & Answers

As answered by people managing Savvy Scratch and React Engine.

What makes your product unique?

Savvy Scratch's answer

Savvy Scratch treats scratchers like a changing market, not a static product, and gives everyday players a way to act with more logic and less guesswork. Built by a long term pro gambler so you know you can trust the math.

Why should a person choose your product over its competitors?

Savvy Scratch's answer

Savvy Scratch is the only scratch-off lottery analysis app built by someone who has made a living beating games of chance. 20+ years of poker, blackjack card counting, and casino advantage play, applied to the one lottery product that actually behaves like a counted deck. Real-time prize-remaining data across 19 states, every active game rated Good, Neutral, Bad, or New so you know which tickets still have jackpots available and which ones are dead money. Free tier shows Bad and New games. Full access $5/month or $50/year, 30-day worry-free guarantee.

How would you describe the primary audience of your product?

Savvy Scratch's answer

Recreational scratch-off players who spend $20โ€“$200+ a month on tickets and are tired of buying blind. They already play, they're not looking to be sold on the lottery, and they don't trust systems or lucky number gimmicks. What they want is the same thing a card counter or a serious poker player wants: to know which games are live, which are dead, and where to put their money. Skews toward adults 30โ€“65 who appreciate data over hype and would rather skip a dying game than keep feeding it.

What's the story behind your product?

Savvy Scratch's answer

I spent 20+ years making a living at games of chance. Poker, blackjack card counting, a handful of casino advantage plays. Over $500K in lifetime winnings, none of it from luck. Somewhere along the way I noticed that scratch-off lottery tickets are structurally the closest thing the gambling world has to a counted blackjack shoe. Fixed print run, fixed prize pool, and as prizes get claimed the remaining tickets drift away from what the back of the pack advertises. Every state lottery publishes the data to figure this out. Almost nobody reads it, and the tools that existed were built by developers who had never placed a real bet. I built Savvy Scratch to apply the same advantage-play framework I used at casino tables to a game millions of people already play, so they can stop funding dead games and start putting their money where the edge actually sits.

Which are the primary technologies used for building your product?

Savvy Scratch's answer

Next.js 15 (App Router) on the web, React Native with Expo for the iOS and Android apps, Supabase for the database and auth, Stripe for subscriptions, Vercel for hosting, Sanity for content, and RevenueCat for mobile subscription management.

Who are some of the biggest customers of your product?

Savvy Scratch's answer

Savvy Scratch is a consumer subscription product, not a B2B tool, so customers are individual scratch-off players rather than companies. The user base spans all 19 covered states, with the largest concentrations in Texas, California, Florida, and New York where scratch-off play is highest.
