ANNAPOLIS -- Eleven new instant lottery games will be introduced in Maryland during the next year as part of an effort to increase ticket sales by offering players more ways to win.

The first two games were launched this week and are designed to raise $8 million to benefit the Maryland Stadium Authority.

"We have found that sales are definitely enhanced by having multiple games, and that is the trend of the industry," said lottery spokesman Carroll H. Hynson Jr.

Of the 11 new instant games planned for introduction between now and June 30, 1991, four are expected to deliver $24 million to the stadium authority.

The lottery agency ran six instant games in the last year. Four games were dedicated to the stadium authority, raising $24 million. Another $16 million was raised for the authority from instant games in fiscal 1988.

The Camden Yards baseball stadium being built in Baltimore is expected to cost $104.5 million.

Hynson said many of the new games will be scaled down, offering fewer tickets and shorter life spans than past instant games. Some will last as little as four or five weeks instead of 10 or 11. The lottery agency frequently runs several games at once.

The two games to be introduced Monday are called "Ca$h Explosion" and "Baseball."

Ca$h Explosion will offer players $5.9 million in prizes, in amounts ranging from $2 to $10,000 for a $1 ticket.

The odds of winning one of the 12 top prizes are 1 in a million. The odds of winning a $2 prize are one in 9.7. Intermediate prizes of $5, $25, $50 and $500 are also available at adds ranging from one in 56.8 to 1 in 50,000.

The game is played by scratching a coating from six squares. If the dollar amounts on three of the squares match, the player wins that amount.

Twelve million Ca$h Explosion tickets will be sold. Hynson said the game will be reissued in new versions periodically during the year.

The new Baseball game will offer players a top prize of $1,000, and there will be 120 chances to win, or 1 chance in 100,000.

In all, Baseball players will collect $8.2 million in prizes, in amounts of $2, $5, $25, $50, $500 and $1,000. The odds range from 1 in 9.7 for the $2 prize, to 1 in 10,000 for the $500 prize.

The game is played by scratching the coatings from four bases on a baseball diamond. If any number on the bases matches the number in a separate box labeled "Your number," the player wins the amount in yet another scratch-off box.

Twelve million instant Baseball tickets will be available for sale.
