It’s boom time for online gaming companies as more people stay indoors. Firms such as Adda52Rummy and Paytm First Games are recording a 50-200% increase in their month-on-month user base. Startups like Gamerji, Rein Games and Poker Dangal are also seeing a spike in engagement. But it’s slump time for fantasy sports sites that rely on live sporting events, and a spate of cancellations have kept users away. A Google-KPMG report says India will have 628 million gamers by 2021 and the online gaming market size at around $1.1 billion.
