The idea is to place like slot machines at check out. At the time of check out customer tries his/her luck on the slot machine which could be computer based or physical machine. Customer may get coupons, discounts, free items ,rebates etc. based on what they get when they use the slot machine. A further extension to the idea could be puzzles ,quizzes etc that are displayed in the store. Customer can try it out and if they succeed ,they will be rewarded by an incentive. At the check out for instance a question will be posed on the touch screen.... and if the customer gets it right he can be rewarded with a discount. Shopping experience can be made more fun, creative, entertaining and engaging by deploying such elements in store. This would be dynamic experience that is both intellectually stimulating as well as makes store a happening place
