Study aim: Assessment of feasibility of using own computer software "Game" at competitions. Material and methods: The data were collected during Estonian championships in 2006 for male volleyball teams of the 13-15-years age group (n = 8). In all games, the performance of both teams was recorded in parallel with two computers. A total of 19 games were played and 38 recordings were made. Results: Summing up the performance of all the elements of the game by both winners and losers, we can say that the winners surpassed the results of the losers considerably. Conclusion: The software "Game" used by us might be recommended for use at other similar competitions. Its advantages are low cost, simplicity and immediate availability of information for the coach.
