Texas Lottery EV

What “expected value” means

Expected value (EV) is the average result of a bet if you could play it millions of times. For a $1 lottery ticket, it adds up every possible outcome — the jackpot, each smaller prize, and the most common outcome of all, winning nothing — with each one weighted by its odds. The figure on every card above is the expected value of $1 played: −55¢ per $1 means that, averaged over all outcomes, you lose 55 cents of every dollar you spend on that game. Wins and losses are both already in that number — there is nothing left to subtract.

Why the games are almost always negative

Lotteries pay out less than they take in, so on an ordinary day every game’s expected value sits below zero, and what changes is how far below zero each game sits. The exception: when nobody hits the jackpot for a long stretch, the prize can accumulate until a game’s expected value briefly climbs above breakeven — you can spot those runs in the history chart where a line crosses the 0¢ mark. Even then, the odds of any single ticket winning are as long as ever; a positive average is carried almost entirely by one enormous, enormously unlikely prize. This terminal doesn’t find you a winning ticket; it finds the game that loses the least right now, so if you’re playing for fun anyway, you can pick the least-bad option.

Why the numbers change from draw to draw

When nobody wins, the jackpot rolls over and grows, which pushes expected value up. Working against that: bigger jackpots sell more tickets, so the chance of splitting the top prize rises, and taxes take a larger share of big prizes. The values here are computed after tax for a Texas resident, on the jackpot’s cash value rather than the advertised annuity — which is why they move with every draw.

How to read the terminal

Each card in Today’s Games shows a game’s expected value per $1 for the next draw, and the banner highlights today’s least negative game. Expand a card’s breakdown for the prize-tier math behind the number, and compare the base ticket against its add-on where one exists. In the history chart, solid lines are past draws, dashed lines are the projection if no one wins the jackpot, and the 0¢ line is breakeven — the closer a line runs to it, the less that game loses.
