The grand prize for subsequent mystery mutuel voucher promotions will be increased by $250,000 until the grand prize is redeemed.Mystery mutuel vouchers are coded tickets worth from $2 to $1.75 million that are distributed in local markets via direct mail. Since last year, more than $8 million worth of vouchers have been circulated, resulting in double-digit increases in pari-mutuel handle and attendance at most participating sites compared to the same weekend date from the prior year.
