This paper considers the advertising, pricing, and service decisions simultaneously to coordinate the supply chain with a manufacturer and a retailer. The amount of market demand is influenced by advertising, pricing and service decisions. In this paper, three well-known approaches to the game theory, including the Nash, the Stackelberg-retailer, and the cooperative game are exploited to study ...

The constrained nature of Mobile devices imposes great challenges on effective user interfaces for game playability. This paper addresses the issue controlling large set of characters on small screens with constrained mobile keys. To this effect we implemented the a mobile version of the Mauritian Domino ( MomoDomino) game consisting of 27 dominoes to test our novel interface design for the con...

Three vulnerable subgroups of players (non-gamers, resistant players, and females) were studied to understand how each approaches and plays serious games. We explore forced (required) play using four different online casual games. Our research strongly suggests that the most important threat to a serious game’s impact is when players dislike the game. Serious games are likely to be least effect...

The Bulgarian solitaire is a mathematical card game played by one person. A pack of n cards is divided into several decks (or “piles”). Each move consists of the removing of one card from each deck and collecting the removed cards to form a new deck. The game ends when the same position occurs twice. It has turned out that when n = k(k + 1)/2 is a triangular number, the game reaches the same st...

Mathematics is a system for representing and reasoning about quantities, with arithmetic as its foundation. Its deep interest for our understanding of the psychological foundations of scientific thought comes from what Eugene Wigner called the unreasonable efficacy of mathematics in the natural sciences. From a formalist perspective, arithmetic is a symbolic game, like tic-tac-toe. Its rules ar...

This paper describes a new large-scale motion capture based game that is called Squidball. It was tested on up to 4000 player audiences last summer at SIGGRAPH 2004. It required to build the world’s largest motion capture space, the largest motion capture markers (balls), and many other challenges in technology, production, game play, and social studies. Our aim was to entertain the SIGGRAPH El...
