Double Play, explained

The mechanics

On Florida Lotto, Double Play re-draws six numbers right after the main drawing. Your same picks — and your same 2X–10X multiplier — play again. Top prize: $250,000 flat; the lower tiers are the base game's prizes at slightly richer values, multiplied as usual; matching 2 still wins a free ticket.

On Powerball, Double Play is its own drawing with a fixed ladder topping out at $10 million — no annuity, no rolling, no splitting a moving target.

Why fixed prizes win the per-dollar fight

The base ticket's value is dominated by a jackpot that (1) is an annuity you'd take at ~45 cents on the dollar, (2) loses 37% to federal tax, and (3) gets split more often exactly when it's biggest. The add-on's ladder suffers none of that — its expected return is a constant you can print.

• Florida Lotto Double Play returns 71.1% per $1 right now (Uses your ticket's multiplier (E[m] ≈ 3.35, estimated from observed winners).) — the base $2 Lotto play returns 25.2% at the current jackpot.
• Powerball Double Play returns 53.4% per $1 — a constant, whatever the billboard says — the base $2 Powerball play returns 31.5% at the current jackpot.

Live threshold: base Florida Lotto only out-returns its Double Play add-on above a $89.9M jackpot. Below that line, the add-on is the better half of the ticket — recomputed on every data refresh, not a stored claim.

The honest caveat

"Better half of the ticket" is a relative claim. Every figure on this page is under 100¢ per $1 — the add-on loses money slower, it doesn't make money. If the question is "how do I lose least per dollar of lottery entertainment," Double Play at a low jackpot is one of the stronger answers in the draw-game aisle. If the question is "should I play," the math has never once said yes.
