START WITH YOUR GAME
See what your chosen pool can cover
Choose a lottery, then choose how many numbers you would put in your group. We explain the answer in plain language. This page does not pick numbers or make a new wheel. Digit, Keno, and special-format games need different math and are not listed here.
Fantasy 5 Evening · 18-number pool
The numbers below describe main-number coverage only.
Math says a wheel cannot use fewer lines than this. It does not say a wheel this small exists.
Every possible ticket from your chosen numbers.
Each distinct line has the same exact-match chance in a fair draw. A wheel organizes coverage; it cannot make the winning numbers enter your chosen group or promise a prize. Bonus balls and add-ons are separate.
THE MATH WITHOUT THE MYSTERY
What these answers mean
One idea at a time. You do not need to be a mathematician to use the calculator.
First, choose your numbers.
The pool is the set you hope contains some of the next draw's winning main numbers. For a Pick 6 game, you might choose 18. No wheel can force winning numbers into that set.
Every possible ticket.
A full wheel plays every distinct line of the game's pick size from your pool. The count is exact. It can become expensive fast.
Fewer lines, specific coverage.
A reduced wheel uses fewer ticket lines. For example, “4 if 5” means one line gets at least four main numbers right if all five winners are in the group you chose.
What cannot be beaten.
Think of the floor as a fence: you cannot go below it. But reaching the fence may be impossible. A real wheel needs actual ticket lines that pass a coverage check.
Will enough winners reach your pool?
For a fair draw, we can calculate the chance of the pool condition occurring. That is separate from the wheel's conditional assurance. Both matter.
Keep it separate.
Powerball, Mega Millions, and other bonus-ball games have another draw. This calculator models main numbers only; it does not claim a bonus-ball match or jackpot odds.
A FIVE-MINUTE EXAMPLE
Why 130, 214, and 8,568 are all different
Imagine you choose 18 numbers for Florida Fantasy 5 Evening. Each ticket uses five. If you bought every possible five-number ticket from your 18, that would be 8,568 lines.
Suppose you want a smaller wheel that gives you at least four matches on one line if all five winners are in your 18. Math proves it needs at least 130 lines. But 130 is only the starting limit; it is not a wheel anyone has shown here. LottoExpert has a checked 214-line wheel for that exact promise. We have not proved that 214 is the smallest wheel possible.
First, all five winners must land in your 18-number group. In a fair 5-from-36 draw, that happens about 1 time in 44. The 214-line wheel then assures at least four matches on one line. Getting all five on one of those 214 lines is a different event: about 1 time in 1,762 drawings, assuming its lines are distinct and every draw is equally likely.
FOR THE CURIOUS
Show me the mathematics
The calculator is transparent about what it can prove and what it cannot.
How is the full-wheel count calculated?
For a pool of v numbers and k main numbers per line, the full wheel has C(v,k) = v! / (k!(v-k)!) lines. Order does not matter and numbers do not repeat.
How is the minimum-line floor calculated?
For an assurance of t matches if m winners are in a pool of v, one line of k numbers can cover at most A = Σj=t…min(k,m) C(k,j) C(v-k,m-j) qualifying winner sets. There are C(v,m) such sets, so at least ceil(C(v,m)/A) lines are required. This is a necessary bound, not a construction or proof of optimality.
How is the pool-condition chance calculated?
If the game draws k main numbers fairly from N, the chance of exactly x landing in a chosen pool of v is C(v,x)C(N-v,k-x)/C(N,k). We add the cases with x ≥ m. Every possible pool of the same size has the same chance under a fair draw.
Why is the 130-line floor not the same as a real wheel?
The 130 figure is a limit, not 130 tickets ready to play. A real wheel needs actual lines checked against every qualifying result. LottoExpert has one checked 214-line example for an 18-number, Pick 5, 4-if-5 question; that does not prove 214 is the smallest possible. Prize rules and bonus balls are separate.
FROM MATH TO A REAL SYSTEM

Use the calculator to understand the minimum and the odds. Then open a real LottoExpert wheel, check its exact “if” condition and line count, and decide whether it fits your budget.
For education and entertainment. Lottery draws are random. Conditional coverage is not a prediction, a guaranteed prize, or a reason to spend beyond your budget.
