Shark is a simple game of high/low with a few improvements.

You are dealt nine cards face down. As each card is turned up, you prompted to guess if the next card will be higher or lower. If the next card is of the same rank, the player loses. Aces are always low.

If you reach the 5th card, you will have the option to cash out early for a lesser prize. However if you continue on you must reach the 9th card to win. (Hint: The prize pool for getting 9 in a row is much greater than the possible prizes for a 5 card win)

If you do not like your current card, you are allowed once per game to change the card. Doing so however will deduct half of your bet, potentially resulting in a lower payout should you win.

There is a rare and special Shark Card with a 2% chance to make it into the deck. If you turn up this card at any point during the game, you automatically win and immediately advance to prize selection.

If you reach the 9th card, turn up a Shark card or cash out early at the fifth card, you will be prompted with three mystery prize boxes to choose from. Clicking one will open your reward and also reveal the other prizes that you did not choose.
