4) Double/Triple the payout with certain combinations: e.g., Double/Triple Diamond, or Blazing 7’s.

5) Hit & Run--3-5 max. spins for return. In addition, 3-5 max. spins after a large jackpot win. 

6) Progressives:  Offer increasing jackpot $$ dependent upon amount of monies played through the linked bank or carousel of slots.

7) There are two levels of progressive jackpots -- primary and secondary -- with many graduated jackpots and pay symbol possibilities.

8) A primary jackpot, displayed in large neon, is the top prize offered for a specific win combination.

9) Secondary jackpots are displayed on smaller screens and hit more often, albeit lower payouts.

10) Progressives, online and off, are found in one casino, or several participating casinos.
After a progressive jackpot is hit, the meter automatically resets to the base jackpot amount.

11) Strategy: Before playing any single group of progressives, check out the primary and secondary jackpots, and then compare other progressives online and off for the best payouts relative to their starting amounts.

12) Look for Progressive jackpots that are paid instantly.

13) Bonus Slots: Multi-lines offer a ‘second chance’ video bonus screen round.
Wild X Multipliers are Bonus reel slots.

14) Bonus Multi-lines: screen shows at least 25 graphic symbols or characters, more than other slots.
At least 5 or 9 paylines and up to as many as 50 paylines may be played.

15) Available in penny to dollar+ denominations online and off. Frequent payouts, usually every 2-3 spins.

16) Scatter pay wild symbols pay anywhere on screen’s criss-crossing pay lines.

17) Use Help Menu to determine grid of various paylines and payouts for matching symbols.

18) Bonus Reel Slots or Wild X Multipliers feature multipliers, free spins and possibly a fourth reel or top box. These bonus slots are popular with people who like to play traditional slots.

19) Strategy:  You do not have to play maximum coins all the time, unlike basic and progressive slots.

20) Play 1-2 coins/line, activating all paylines, until you build some credits. Then the occasional maximum coin spin is not a high risk.

21) Play New bonus slot versions offered online and off as often a new product will have better payouts.
