Online tools and platforms extend a great variety of opportunities in the classroom, including General English and Business English classes. The outbreak of the pandemic in 2020 and the lockdown that followed urged many educational institutions and educators to transfer their teaching materials into digital form, thus enabling the smooth shift to online teaching modality. The research addresses the issues related to the advantages of two main online platforms, namely Kahoot and Blooket, employed during Business English classes at the Armenian State University of Economics (ASUE). During the research, the authors used statistical, descriptive, and comparative analyses to collect feedback from 58 students and responses from in-person interviews with 18 lecturers teaching Business English at the same university and reveal and compare the advantages and disadvantages of two considered platforms from teachers’ and students’ perspectives. The results showed that the advantages of the Blooket platform far outweigh those of Kahoot in terms of accessibility, ease of use, and affordability.
