    We have studied the occurrence of behavioural changes in chimpanzees whilst adding gaming aids to their living environment. At the beginning of the study, we encounter the spread of pneumonia in the Ljubljana zoo, where two younger chimpanzees and adult females lost their lives. The study included three female chimpanzees. After this tragic event we took a break in our research to give the chimpanzees some time to recover. We began recording a month later. After six months of observation, we noticed some positive changes in their behaviour. We noticed that the number of abnormal behaviours significantly reduced in all three females. The interaction between the chimpanzees and visitors of the ZOO decreased. We also noticed a reduced interaction between female chimpanzees. Aggressive behaviour of the chimpanzees during our observations was not noticed. During the whole process of observation we noticed that each of the observed female chimpanzees had its own desired set of gaming aids. Mojca, the oldest of the observed female chimpanzees, was especially attracted to games with manipulative and unusual combinations of game play. Neža and Nika were more intrigued by games (usually a set of obstacles) which promised a food treat after getting to the end of the game (overcoming the obstacles). During the observation we noticed some unexpected defensive behaviour, which might be the result of the negative relationship of the chimpanzees towards the presumptuous visitors. During the winter time we haven’t noticed such defensive behaviours, because of the reduced amount of visitors.
