Much better than just tossing dice and playing a strategy to see how well it does.
The AI engine is working great.
“I couldn’t stay away and ran more strategies! Your AI engine is working great. The fast setting is functioning really good with the strategies I have been trying now. Good work!”
The best craps site.
“The best craps site on the Internet. It’s all about the math as opposed to anecdotal comments.”
Clear enough to follow.
“I like how you break things down into simpler facts and explain things thoroughly. Keep up the good work.”
Beats trial and error.
“Much better than just tossing dice and playing a strategy to see how well it does.”
Many times what it costs.
“Studio is a terrific tool for me. The material you make available for free, and the additional material for members only, is extensive and will satisfy many, if not most, people. The Studio is a quantum level advancement as an aid to serious gamblers. The profit I have made from studying DiceData is many times the cost you charge.”
Studio is simply amazing.
“Studio is simply amazing. I gave it a basic strategy and a more complex one. I thought the more complex one would be the better strategy, but it turns out the simpler one was better. Thank you for building it.”
Like having a craps guru on call.
“I can’t say enough great things about Studio. It’s like having the craps guru at my beck and call. I can test all my strategies and logic with the chatbot, and it’s absolutely fantastic.”
Working with Matthew was easy.
“Working with Matthew was easy. I submitted my methodology, had a couple of back & forth e-mail exchanges to clarify, and in a short time, I received the results. I learned that my new strategy was riskier than the methodology I have used for years. My custom scenario was well worth the investment.”
Turnaround was incredibly quick.
“I commissioned Matthew to analyze a strategy I had been working on. Turnaround time was incredibly quick. Communication was easy and professional. Matthew asked insightful questions to help clarify the requirements. His analysis will definitely help me fine tune my playing style. I'm a very satisfied customer.”
This is real math.
“Wow, if you play craps, and wish to see exactly what your system will produce, this is the fellow to talk to. This is not from the table, winning or losing overtime, this is real math. Nothing replaces intuition and a little bit of luck, however, this analysis will give you the best indication of reality.”
A customer came in with a conservative strategy built for casino comps.
They expected a verdict on how cheaply it bought table time.
Their pressing rules gave the bots a small share of nights that ran to several times the starting bankroll.
The report put a number on how rare those nights were, which is the part no session at the table can show.
We iterated on a pressing strategy over several weeks.
Each version ran against the same dice as the last one.
The runs kept surfacing the same weak point, invisible from the table because it only cost money on one specific sequence.
The version they kept holds a lower house edge than the one they walked in with.
A player brought their modified Martingale.
They wanted it tested with the stop-loss limits they actually use.
The report showed how often the progression hit the table maximum, and what each reset cost when it did.
Adjusting the tier progression cut the expected loss rate substantially.
Or start with one from the vault and modify it with your win goals and stop losses.
Create an experimentThe bots place bets just like a player would, at a real table.
Sample report, 30 shooters a night. Yours will use your numbers.
Games
Any house: odds multiples, field pays, and the place and hardway paytables.
Points on 2, 3, 11, and 12, at the payouts the house actually runs.
Every wheel the floor runs, at its real paytable.
Eight-deck shoe, dealt with the real burn and cut-card procedure.
The four personas
A comp grinder and a jackpot hunter should never touch the same system. Every report rates each system for all four players. Find yours, then start with the systems built for it.
Steady wins
Frequent small wins; cashes out at a modest target.
Action & fun
A simple, affordable play with a real shot at a nice win.
Time & comps
Long, low-edge play that racks up table time and comps.
The big score
Chases one huge win, accepting a steep edge and losses.
Bankroll Needed
Every report answers with two numbers, measured from what the bots actually had to pull out of pocket. A bet paid for by an earlier win costs nothing, so this is the real cost of a seat, not the total wagered.
Usually Sufficient: 3 of every 4 bots never needed more. Nearly Always Sufficient: 19 of 20 never did.
Long Term
A system can be tuned to win night one; quit-while-ahead rules do it on purpose. Long Term is the honest test: the bots take the same system back up to 500 visits, and the chart tracks how many are still ahead. That slope is the house edge doing its work.
The full curve, visit by visit, is on every report's Long Term tab.
Comps
Casinos don't rate a player on what they lose. They rate on theo, the loss the house expects: average bet, times hours, times decisions per hour, times house edge. Comps are a cut of that number. The report computes the real thing from every bet the bots placed, then checks it against what the pit would guess.
Craps is where the guess goes wrong: multi-roll bets, bets that follow the puck, prop bets the rating can't see. Some systems earn less than they should. Some earn more. The full model is on every report's Comps tab; members can tune every input.

Find out which one actually comes out ahead, and by how much. Ever wonder if you should have pressed instead of pulling down? Play both on the same night and find out.
Every variant of an experiment plays the exact same dice, so the only thing that differs is the bet.
Create an experimentThe Lie, Line vs Place · 100,000 bots, identical rolls
The dice are yours. Throw whatever you want at a system from the Vault and see how the bot takes it: what it bets next, what it has to say, where its stop rules kick in. Hand it a hot streak. Force a cold table. The fastest way to learn a system before a dollar rides on it.
Test Drive is bot number one. The report is what happens when 100,000 play the same rules on their own.
Compare is the power tool behind the vault: every variant ranked side by side, sortable by persona fit, win profile, and setup. Find the systems that fit how you actually play, then open the full report.
Free to browse, no account needed: every system and its ratings. Members see every number: the dollar columns for the typical night and the best night, plus the full filter suite.
