Lottery odds come from simple counting. If a game asks you to choose 6 numbers from 49, there are 13,983,816 different sets of six — so one line has a 1 in 13,983,816 chance of matching them all.
Why bonus balls make odds longer
Games with a separate bonus drum multiply the two counts together. Five from 69 gives 11,238,513 sets; add one bonus ball from 26 and the total becomes 292,201,338.
What buying more lines really does
Ten different lines give you ten chances out of the same total. It improves your odds, but only slightly — ten in 292 million is still very long.
Every combination is equally likely
1-2-3-4-5-6 has exactly the same chance as any other line. It just feels less likely because it looks like a pattern. The odds panel beside every generator shows the exact numbers for each game.
