Sudo won't help you.
Right click on the executable file -> navigate to settings -> tab permissions -> set mark at "Allow executing file as program". Enjoy the game.
Already tried that nothing happens when I execute or double click after markinh allow as executable, that is why I tried using terminal.
Don't know if this is related but I saw this on google.
""You can't do that directly on Linux on x86_64 with a 32bit kernel. You need a 64bit kernel to be able to run 64bit code. (Note: kernel. You can have 32bit userland running on a 64bit kernel, and install support for 64bit binaries. How easy this is depends on the distribution. Example here for Debian.)
Some virtualization software is able to do that (with restrictions on the type of CPU you're using), and emulators can do that too. But to run it natively you'll need a 64bit kernel.
Since most 64bit distributions out there have 32bit support (either by default or installable), that's what you should be using if you need to run both 64bit and 32bit binaries on the same OS.""
Can someone verify if it will not work at all on my laptop which is only 32bit
