LottoBook

LottoBook is a reference for people who play the lottery and would rather know what they are buying. It does not sell tickets, take a wager, or pay anything out. It has no system, no lucky numbers, and nothing to sell you about your chances. What it has is the draw history, the exact odds, and the one figure almost nobody publishes: what a ticket is actually worth tonight. WORTH PLAYING Every drawing ranked by what a ticket actually returns, after split risk and after tax. Every one of them returns less than it costs. That is the nature of the game, not a bad night, and the app says so plainly. What genuinely changes from draw to draw is how much less, and a rollover can be worth three times what an ordinary draw is. THE NUMBERS Frequency for every ball, over 163,914 real draws across eighteen games. The grid is built to show you that frequency means nothing: a fair game renders as a wall of identical cells, because that is what fairness looks like. Counts are scoped to the game's current rules by default. Powerball has been three different games since 2010, and an all-time chart mixes draws from a smaller drum where the higher balls never had a chance to appear. PICK NUMBERS Five ways to choose, and the app tells you which of them do anything. Four do not, and say so on the card. The one that does is Least Shared, and it does not improve your odds either: it avoids the numbers people pick by hand, so a win is less likely to be split with somebody else. That is a real effect and a modest one, and the app reports the small true number rather than a flattering one. CHECK A LINE Check any saved line against any past draw. For California games it reports the real pari-mutuel amount paid at that tier on that specific draw, which is not the figure on the national prize chart. On one recent draw the chart promised $1,000,000 for matching five; California paid $125,670. For states that publish results but not payouts, it reports the tier and no dollar figure, rather than filling the blank from the wrong table. CALIFORNIA, NEW YORK AND TEXAS Eighteen games, with every matrix derived from the state's own published history and checked against it rather than copied off a marketing page. WORKS OFFLINE The full draw archive ships with the app. LottoBook cannot improve your chances of winning, and does not claim to. Every combination has exactly the same chance. If you play anyway, this tells you what you are actually buying.
