Versus Sports Simulator is an interactive tool that lets you simulate matchups between any two teams across multiple sports. Instead of running thousands of random simulations like a Monte Carlo model, Versus uses a proprietary mathematical model to project the most probable final score based on team ratings, stats, and historical performance. You can run simulations with either team at home, on the road, or at a neutral site. For added flexibility, you can randomize outcomes by applying variance or adjust offensive and defensive sliders to test "what-if" scenarios.
We publish the record rather than describe it. In college football, Versus has put a win probability on more than 20,000 games across five complete seasons, and in every confidence band the share of favorites that actually won lands within about two percentage points of the odds we stated. The full breakdown, band by band and season by season, is on our win probability accuracy page, and it recalculates as each season finishes.
That measures game outcomes: when Versus favors a team, how often that team wins. It is not a measure of performance against a sportsbook spread, which is a separate and much harder question. Accuracy also varies by sport, and it is highest where the gaps between teams are widest.
Most prediction sites focus on expert picks, betting tips, or crowd sentiment. Versus is different. It uses a mathematical model that updates daily by recalculating every team's rating based on the latest game results. Those updated ratings power the site's simulations and score predictions, which are designed to show the most statistically probable outcome between any two teams. Users can simulate games with either team at home, away, or at a neutral location. They can also customize simulations by adjusting offensive and defensive sliders or adding controlled randomness. Versus doesn't rely on opinions or hype — just consistent, transparent math.
Absolutely. Many Versus users are fans, journalists, or data geeks who want deeper insights into team strength, matchups, and performance trends. Whether you bet or not, the ratings are valuable for understanding who's really good — beyond just wins and losses.
The Simulator tool lets you compare any two teams and see projected outcomes based on Versus' team ratings. It shows expected win probability, projected score, and margin of victory. You can also adjust settings like offensive and defensive strength, add randomness, or simulate games at neutral sites to explore different scenarios.
Yes. The Game Simulator works on any two teams in a league whether or not they are scheduled to meet. You choose the home team or a neutral venue, and except in MLB, that choice affects the predicted result.
Team ratings, rankings, and predictions are updated daily for all sports during the regular and post season.
The Versus Sports Simulator uses an advanced proprietary mathematical model to produce a variety of ratings estimates for individual teams. The algorithm takes into consideration:
Performance ranking reflects how well a team has played against its unique set of opponents so far during the season. Power ranking shows how well that team is expected to perform in future games. On a neutral field, a team with a higher Power ranking would generally be favored to win.
Every team carries numeric ratings on a 60-to-99 scale for Overall, Power, Offensive and Defensive performance. Each numeric rating also gets a letter grade, so you can assess a team quickly without comparing decimals.
For college football and college basketball, grades are relative to the team's own division, because the divisions rarely play one another.
The number of stars indicates the team's Prestige — a rolling measure of its performance over the past 4+ seasons. A five-star team has consistently ranked in the top 20% of the league, while a one-star team has been in the bottom tier.
Pro and college football, pro and college basketball (men's and women's), baseball, hockey, soccer, and UFC. Coverage for each sport runs through its regular and post season.
Team rankings, conference and divisional rankings, and team summaries are free for every team in every league. A limited number of predictions and simulations is also free.
A subscription unlocks every prediction for every scheduled game, unlimited simulations, and every team in the simulator.
Many premium users are handicappers or casual gamblers who use the predictions as part of their research. However, we don't recommend using raw predictions alone for wagering — they don't account for injuries, coaching changes, weather, or other real-world factors. The Simulator tool allows users to adjust assumptions for a more customized prediction.
No. Versus Sports Simulator is a ratings and simulation service, not a sportsbook. You cannot place a wager with us, and we do not accept money for bets. Our predictions are model estimates, not guarantees.

Here's what our premium subscribers have to say about Versus Sports Simulator:
Been using Versus to bet games for 5 years. Still the best prediction app/site available. I use it daily.
Love this simulator. I've used AccuScore, predictionmachine, oddshark, and sportline sims — VS is the best.
Versus is truly a state-of-the-art platform. We've been very impressed with the speed and accuracy of the APIs.
Came across this in the last few years. I love simulating cross-level college matchups. Very accurate!
Very accurate model. I've used it as a UFC handicapping tool and it's helped me find betting value consistently.
Versus generates very accurate NCAAF results — better than Sagarin, AccuScore, and others. Great value for the money!
