βοΈ I want to compare bets
Which games and bets actually cost the least, with exact numbers.
Browse by game
Baccarat
Three bets. One answer: Banker at 1.06%. The simplest math at any casino table.
Big Six Wheel
The money wheel by the entrance charges 11-24% for the privilege of not having rules to learn.
Blackjack
The lowest house edge of any table game, but only with basic strategy.
Blackjack Switch
The only blackjack table that lets you swap cards between hands. Push 22 is how it charges you for the favour.
Casino War
The simplest game in the house: one decision, and you always make the same call. A clinic in how an edge is built from almost nothing.
Crapless Craps
The friendliest-sounding craps table is the most expensive one: 'never lose the come-out' quadruples the pass-line edge.
Craps
The only 0% house edge bet in any casino lives on this table.
DJ Wild
Five wilds in 53 cards. You'll make a pair almost every hand, and the bet paying the big multiples is asleep for nine of ten.
Double Down Madness
One card to start and unlimited doubles after; paid for by a dealer 22 that pushes instead of busting. Check the paytable: the same game costs 0.95% or 2.07%.
Four Card Poker
Your best 4 of 5 vs the dealer's 4 of 6. The skill is sizing the raise: 3Γ when strong, 1Γ for damage control.
Let It Ride
Three bets up, and the skill is taking them down. Fully solved: every figure computed from all 52M states.
Mississippi Stud
Three escalating raise-or-fold streets. Solved from scratch: the derivation reproduces the expert strategy, 6-5-suited quirk included.
Roulette
One extra zero nearly doubles the house edge. The wheel you choose is the only strategy.
Slots
A black box by design, so we built a transparent one. RTP, volatility, paytables, and why even 99% RTP loses.
Spanish 21
The 10-spots leave, the comebacks arrive: always-win 21s, bonus payouts, the rescue button. Cheaper than most real blackjack, on its own strategy.
Three Card Poker
One rule, Queen-6-4, is the whole strategy. Plus the flashy Pair Plus side bet that quietly costs more.
Video Poker
The odds are printed on the glass and your decisions move them; read the paytable first, then learn the holds. Our simulator grades every one against the exact solver.
Social Casinos by State
Whether sweepstakes (social) casinos accept players, and how settled the law is, depends on your state. We cover platform availability, the relevant statutes, and recent enforcement for all 50 states + DC, each independently researched and dated.
Comps & cruise casinos
What the casino gives back, what it costs you to earn it, and the one vertical where the numbers are genuinely hard to find.

- Theoretical Loss: the Number That Rates You
- Why Comps Don't Make You a Winner
