Een zaak voor TKKG: De schat van de Maya's... is a detective adventure for children. Same as with other games in the TKKG series, they feature Tim, Kasper, Karin and Gijsje on their case.
This time, two jade masks from Hunapuh, from the Mayans, get stolen from a museum and it's their job to find out who did this. The game features simple game point and click game mechanics. Players can choose one of four characters to take with them and choose a location to search or to question people.
Any of the four main characters can get different results out of a questioning, or may or may not be able to solve a certain puzzle. So it's important to go to the same location with different people. Gaining evidence and testimonies is vital to cracking the case.
