Innovations are considered crucial in boosting the growth of regions. Similarly, tourism is an important regional development tool especially in areas with no industrial potential.Research on tourism innovation has been scarce until the very recent years and the local economic impacts of innovation in tourism studies remain unexplored. This study addresses the innovative ICT application, a mobile game, and its significance as a tourist attraction in Pielinen Museum in Lieksa, a peripheral town in Eastern Finland. Pielinen Museum has a substantial effect on Lieksa municipality economy and the average visitor expenditure is substantially higher than expected based on previous studies on other local attractions. We conclude, however, the game is not known by general public to attract visitors. From museum's point of view the innovation will not have extensive influence as a standalone, one time effort. It needs better integration into museum's general public image and continuous support and updating for both contents and technique. Extensive networking with existing regional visitor attractions for increasing the publicity without excessive costs is highly advisable.
