As described above with reference to the game system 1 according to the embodiment, one of game condition is selected from among a plurality of game conditions in accordance with prediction data corresponding to predictions input by respective players, as shown in FIG. 11, and a common game is performed according to a selected game condition. As mentioned above, game conditions for a game which is played for paying out awards change according to the prediction data predicted by the players. For instance, in a horseracing game system, when players make predictions on the game result and bets, the number of jockeys mounted on a popular horse is increased, and the weight carried by the horse becomes heavier. The game of horseracing is performed in such a handicapped state. Thus, a game condition for a game changes. Since a game status varies according to predictions made by the players, it becomes more complicated for the players to make predictions, which in turn causes the players to enjoy the game further. Therefore, there can be provided a game system which makes players enjoy a game further by means of making it complicated for the players to make predictions.

Moreover, according to the game system 1, when a piece of specific prediction data is stored, in a predetermined proportion, in the plurality of pieces of prediction data, there is selected a special game status having game result influence data which make a game result acquired from specific prediction data more disadvantageous than game results acquired from pieces of the other prediction data. Thus, when an unbalance has arisen in the predictions made by the players, a special game status which is disadvantageous for a game result is selected aside from awards. For instance, in a horseracing game system, when prediction data pertaining to prediction of winning of a certain horse (e.g., Haru-urara, Oguricap, Hiseiko, or the like) are popular, a change is made to achieve a special game status which is disadvantageous to game results; for example, changes in various factors, such as the parameters of the horse (e.g., an increase in the weight of the horse), the status of a racecourse where respective characters (horses) run a race, and others.

Thus, a game status changes according to predictions, which makes it complicated for the players to make predictions and which makes players enjoy the game to a much greater extent. Therefore, there can be provided a game system which makes players enjoy a game further by means of making it complicated for the players to make predictions.

In the above description of the embodiment, it is described that the game system 1 is configured to allow the players to “input” the game medium into the player terminals 30 (game medium input unit), more specifically, into the coin insertion slot 732, at the insertion process (step S2), and that the player's prediction (bet) is made in the game execution process (step S5). In the game system 1 described as the embodiment, the deposit game medium count is determined as a predetermined proportion of the total number of the game medium “input” into all of the player terminals 30.

However, the game system 1 may alternatively be configured that the deposit game medium count is determined as a predetermined proportion of the total number of the game medium (coins, medals, or credits) being bet (predicted) in all of the player terminals 30 by each of the players for each round of the game. When the game system 1 is thus configured, the input of the predictions (bet) into each of the player terminals 30 is considered as the “input” of the game medium.

The present invention is not limited to the previously-described embodiment. The game system according to the present invention may be applied with various improvements or alterations without departing from the scope of the claimed invention.

As described above, according to the game system, a game status changes according to predictions, which makes it complicated for the players to make predictions and which makes players enjoy the game to a much greater extent. Therefore, there can be provided a game system which makes players enjoy a game further by means of making it complicated for the players to make predictions.
