oTree can do it

oTree is a behavioral research platform that lets you build any kind of task or interaction, even if it's something nobody else has made before. Our starter library shows oTree's flexibility: there are simulations of social networking and online shopping apps, psychological tasks such as Stroop and flanker, multi-player recreational games like poker and live word search, a continuous-time double auction market, classic game theory games like the prisoner's dilemma, and surveys.

oTree has been used in over 3000 publications.
