Introduction

In my continued effort to lift the veil of secrecy behind slot machines, I present the following analysis of the IGT game Lucky Larry's Lobstermania. The information regarding the design of this game is taken from the academic paper PAR Sheets, probabilities, and slot machine play: Implications for problem and non-problem gambling by Kevin A. Harrigan and Mike Dixon, University of Waterloo, Waterloo, Ontario, Canada.

The authors of the paper obtained par sheets for the game through the Canadian Freedom of Information and Protection of Privacy Act. I applaud the government of Canada for this release. The purpose of this page is to further the analysis of Lobstermania beyond what was presented in the Harrigan and Dixon paper.

It should be noted there are other versions of Lobstermania besides this one. As far as I can tell they differ by small changes to the pay table and details of the bonus round.

Reel Strips

Harrigan and Dixon give the symbol distribution for two Lobstermania par sheets, one for 85.0% and the other for 96.2%. Both are presented below. Notice how the 96.2% version has more high-paying symbols and that any given symbol is distributed more uniformly across the 5 reels. To illustrate that the distribution is more choppy in the 85.0% version, notice that the number of clams per reel on the 85.0% version is 10,8,3,4,7. On the 96.2%, the distribution is 6-6-5-6-6. However, the number of key symbols (wild, scatter and bonus) are the same in both games.

Lobstermania Symbol Distribution — 85.0%

Total	47	46	48	50	50

Harrigan and Dixon do not indicate the exact reel stripping. However, as long as the scatter symbols are not so close on the same reel that they can appear at the same time, the symbol order does not matter for this game, as well as for most video slots. The following reel stripping is hypothetical, based on the 85.0% version.

The way the game would work would be to choose 5 random numbers, one for each reel, and map each random number to a position on the corresponding reel. For example, for reel 1 the game would draw a number from 1 to 47. For example, suppose this number were mapped to the symbol in the top row. If the random number for reel 1 were 37, then the symbols shown on reel 1 would be a Clam on top row, a Star Fish in the middle row, and a Boat on bottom row.

Pay Table

The next table shows the Lobstermania pay table. All wins must be left aligned. The wild symbol can substitute for any line-pay symbol.

Line Pay Math

There are 47 × 46 × 48 × 50 × 50 = 259,440,000 possible outcomes in Lobstermania. The following table shows how many of these combinations result in each possible win. These figures are the result of a program with five nested loops that tallied the total for each win for each possible combination.

The next table shows the probability of each possible win. This is the number of winning combinations for that win, shown in the table above, divided by the total number of combinations of 259,440,000. The total in the lower right cell reflects a hit frequency per line (probability of winning anything) of 3.25%.

Scatter Pay

The player gets credit for a 'scatter pay' symbol if it appears anywhere on the screen. Scatter pay wins are based on the total amount bet. The following table shows the number of scatters per reel, total symbols per reel, and the probability of a scatter on that reel, which is 3×(column 2)/(column 3). The reason for multiplying by 3 is there are three visible positions on each reel.

Lobstermania Scatters per Reel

Reel	Scatters	Total Symbols on Reel	Scatter Probability
1	2	47	0.127660
2	2	46	0.130435
3	2	48	0.125000
4	2	50	0.120000
5	2	50	0.120000

The next table shows the probability and contribution to the return for 0 to 5 total scatter symbols. The lower right cell shows that the scatter pay feature returns 10.65% to the return of the game.

Bonus

The player earns the bonus if he gets the bonus symbol on reels 1, 2 and 3 on any active pay line. The following table shows the probability of getting the bonus symbol on each of the first three reels. The lower right cell shows the probability of activating the bonus on any active pay line is 0.06%, or 1 in 1,730. If the player plays the maximum 15 pay lines, then the bonus probability per spin is 0.87%, or 1 in 115.

Lobstermania Bonus Symbols per Reel

Reel	Bonus Symbols	Total Symbols on Reel	Bonus Probability
1	2	47	0.042553
2	5	46	0.108696
3	6	48	0.125000
Product	0.000578

There are three parts to the bonus game, as follows:

• Number of lobster traps.
• Number of lobsters per trap.
• Size/win of each lobster.

There are three possibilities for the number of lobster traps, 2, 3 and 4, each with equal probability. Thus, the expected number of traps is 3.

There are two possibilities for the number of lobsters per trap, 2 or 3, each with equal probability. Thus, the expected number of lobsters per trap is 2.5.

The prize per lobster can be anywhere from 5 to 250. Each prize has an associated weighting, as shown in the table below. The way the game might work is it would pick an integer from 1 to 322 and map it to a weight according to this table. The bottom right cell shows an average win of 44.02 per lobster.

250	5	0.015528	3.881988
Total	322	1.000000	44.021739

The average win per bonus is (average traps)×(average lobsters per trap)×(average win per lobster) = 3 × 2.5 × 44.021739 = 330.163043.

The expected return for the bonus feature is (bonus probability) × (average win per bonus) = 0.000578168 × 44.021739 = 0.190890.

Summary

The following table summarizes the three ways to win in the game. The bottom right cell shows an expected return of 85.012%. In other words, for every dollar the player bets he can expect to get back 85¢.

Lobstermania Summary

Item	Return
Line Pays	55.278%
Scatter	10.645%
Bonus	19.089%
Total	85.012%

The Harrigan and Dixon paper mentioned they were given par sheets for seven versions of Lobstermania. The available returns were 85.0%, 87.5%, 90.0%, 92.5%, 94.0%, 95.0%, and 96.2%.

Designed and developed by IGT, Lobstermania has made a seamless transition from land-based to online casinos, and the popularity it has enjoyed across the globe has been successfully replicated in this supreme online offering.

Renowned as one of the most fun slot games around,Lobstermania puts players in the shoes of Lucky Larry, alobster fisherman looking for those big catches that he can swap for cold, hard cash. As ever, players are looking to spin those magical combinations that secure a payout; while hunting down those bonus symbols to trigger one of two bonus rounds.

Lobstermania weighs in with five reels and 25 paylines, which is the standard in most online slot games and is a set-up which offers plenty of profit-making potential. Players can bet on each payline and wager up to 75 coins per spin, and all-in-all there is the possibility of scooping up a fantastic jackpot of 50,000 credits. A host of immersive bonus rounds and features also add to the dash for the cash.

To keep the nautical theme rolling, the game’s symbols include lobsters, boats, lighthouses and buoys, as well as the Lobstermania bonus symbol - which really is the one to watch out for. The wild lobster symbol is also a winner as it substitutes for all other symbols on its reel (except for the bonus and scatter symbols), and so helps you to create more winning combinations.

If you are lucky enough to spin five wild symbols across the game board then you will scoop the rather tasty jackpot prize!

Bonus Rounds and Features

Lobstermania features not one but two bonus games that help you to top up your prize kitty and scoop some generous payouts. These are The Great Lobster Escape and The Buoy Bonus.

As the name suggests, in The Great Lobster Escape players need to help Lucky Larry secure the escape of his lobster pals; and you will be rewarded handsomely for each lobster that escapes. However, should one of the canny crustaceans fail to make it then the bonus feature ends.

The Buoy Bonus is triggered when three of the Lobstermania symbols are spun from left to right, and the emphasis here is on catching lobsters, with each one caught rewarding you with cash: the bigger the lobster, the bigger the prize. If you retrieve a cage without any lobsters in it then the bonus game is over.
