Hi I am new to investments and stocks, is there any platform where I can try a trading simulation or like share market game of sorts?

I'm a big fan of TDameritrade's thinkorswim platform, which is commission-free, has a virtual trading capability, and allows you to script stuff. Very powerful stuff, all for free.

Start by knowing yourself first. Why do you want to invest? What is your investment psychological profile like? Will you be able to sleep well at night if the value of your investments plunge? Read up readily available material like the intelligent investor, learn to earn or financial blogs like investment moats. These will give you a grasp of what doing investment is like. The only platforms I know that allows simulated trading is oanda and thinkorswim. The former is meant for forex while the latter only covers US market. Hope this helps

Thinkorswim has a demo account functionality that u can try virtual trading

Used TradeHero before in the past, great way to try out with virtual money. But take note that the experience when trading with virtual money and real money is quite different because of your emotions etc.
