HOW ?

• $5/wager• $0.50 loss per wager• $300/hour• 20 hours/week $6,000• X4 weeks is $24,000/month• X2 players $48,000/month

AWWW SHUCKS EFFECT (NEAR MISS)

– See two 7’s on the payline– The type below can appear 12 times more

often than by chance alone, on each reel– Accomplished by weighting the blanks

which are adjacent to 7’s

SIZE OF SYMBOLS VS BLANKS

• Blanks are smaller but show up on the payline more often

UNBALANCED REELS

• One reel is starved of the jackpot symbol• Aww Shucks effect (Near Miss)• See the Jacks in non-winning positions

NEAR MISSES - RESEARCH RESULTS

• Research shows that near misses have an effect on the player (Clark et al, 2009)

Near Misses enhance motivation to gamble

Near misses activate areas of the brain associated with wins, even though it was not a win

Brain activity correlated with self-reported measures of gambling propensity

LOSSES DISGUISED AS WINS

• Depending on the wager, approximately 60% of “wins” are really losses

• Wager $3,75 and “win” $2.25– Really a loss of $1.50– But the slot machine produces winning sounds

and winning graphics

LOSSES DISGUISED AS WINS

• ‘“The perception is that you’re winning all the time, when you’re really not— you’re putting 25 in and winning 15 back, 45 in and 30 back, over and over.” Randy Adams of Anchor Gaming (Schull, 2005)

• “Positive reinforcement hides loss.” Nathan Leland of Silicon Gaming (Schull, 2005).

• One elderly slots player told me “If I keep winning I’m going to go broke.”

STOP BUTTON

• Stop ButtonsPlayer can stop the reels before 3-5 seconds

Doesn’t affect the outcome

Provides an “illusion of control”

Giving the player an “illusion of control” gives a player a sense of control even when the player fully understands that the outcome is random (Langer, 1975).

CREDITS VS CURRENCY

• Usually your money is shown as credits• Ex: A five cent machines pays 150,000

creditsNot easy to convert to currency

MULTIPLE VERSIONS OF THE SAME GAME

• Payback percentage is not disclosed to the player

• In Ontario, same game can payout between 85% to 98%

• All versions look identical to the player

INDUCEMENTS FOR MAXIMUM WAGER• Various messages on the machine

“Play all 15 lines for maximum excitement”

“Play three credits”

• Some prizes can only be won with maximum wager

HIGH STAKES ROOMS

• Maximum $ 750/spin• Average loss per spin ~ $ 40• A spin every 5 seconds• Average $480 loss per minute• Average $28,800 loss per hour• Average ~ $100,000 for an evening of play (4

hours approx)
