need help with an led string for a lit up version of cornhole.

I'm trying to build a lit up version of cornhole using plexiglass. I'll need a string of 140 something led lights on one circuit, for the outer perimeter. they just need to be lit solid and hopefully be able to be powered by a battery. then I'd like to have another string that will operate when triggered by a bag that goes in the hole. I want them to strobe leading up to the hole with 27 leds running up, then a group of leds going around the hole operating as the last running light. these would operate only after someone scores. I know next to nothing i need to know in order to accomplish this. Does anyone have any advice for the 140 something string first? Probably best I start with the easy stuff. I need a lot of help here, but I'll really appreciate it. When I say I need a lot of help I mean, I even forgot the basics as in resistors and voltages. I'm using 5mm leds with a max current of 20mA Continuous, 50mA peak for 10% Pulse Width.

I thought LEDs were weird about voltage. like they'll always act as one or something like that? So there's no way I can get a string with like 140 lights that works on a battery?

If you rectified a 110V supply, you could run 4 x 35 white LEDs in series, or 2 x 70 with a 220V supply. What do you think? L

What color are the LEDs? Do you have a spec sheet for them or know the Vf (forward voltage drop)?
