How to enable developer settings in android 5.1, instead of LOLLIPOP game I want to  access developer setting in my phone, but it is not showing all settings. It has developer options but there is only one switch button for switching Developer options and USB Debugging settings. I searched on internet and many sites, they said that in LOLLIPOP devices, developer settings are hidden. we can enable them by clicking 5 or 7 on Build-number in About section in the settings. In my phone, when I navigate to Settings>About Phone> there is no option with containing word 'Build'. but when I click 5 or 7 times on Android Version option it open a game of LOLLIPOP instead of developer settings. Can anyone tell me how can I enable developer settings in my android LOLLIPOP phone???
Thank you in  advance....

I have Q-Mobile i6i with android 5.1.
In vanilla AOSP builds, the Build number menu is the last one on the About phone panel. From your screenshot, your device instead has Software version in that location. Try the 5-7 clicks on this area. If that doesn't do anything, or produces a message like "No need, you are already a developer.", then I'm afraid your OEM has removed this ability and given you only minimal Developer options capability in the form of a USB debugging switch. The good part is that it's already enabled so at least you have that. 

Also, the Lollipop game that you found after multiple clicks on Android version is also what happens in normal AOSP devices.
