The idea is to use cards that kanji are printed on and
play a game. It would require cards with a kanji written/printed on one side and info about that kanji written on the back side of the card. Pull one card from the deck, with the kanji side up. Each person gets one point for giving the meaning(s) (some kanji have many meanings), onyomi pronunciation(s), kunyomi pronunciation(s), and giving kanji combinations where that kanji is used. Whoever gets the most points wins. (I do not see how this could be done any way but with paper cards.) It would be necessary to note which are kanji 1-100, 101-200, 201-300, and only use cards with kanji that all players have studied (have written at least ten times). Or group them into first grade kanji, second grade kanji, etc. This is a very effective way to study kanji, and is a lot more fun than just writing columns and columns of kanji by yourself.
I think Skype still works just fine, but I think the latest is Zoom.
Anything works as long as you are writing out each stroke of each kanji. Just cutting and pasting kanji computer images is a huge mistake.
I don't think a pack of blank cards is that expensive, and it is a good investment in your Japanese studies. I also strongly recommend buying a set of printed kanji flash cards similar to the ones in this link. Professionally printed cards like this were a big help back when I was learning kanji.
Lovely little lot of Japanese / English flash cards in their little cardboard storage box. I havent counted the cards - I would estimate around 300. I have pictured just a few of the cards to give you an idea. Good vintage condition. Some minor age wear but no rips, tears or bends. The cards

Another thing about buying blank paper cards and writing all of these things out by hand is that you will learn a lot by doing it.

I want to give some advice. Divide your study of Japanese into three areas: (1) learning kanji, (2) learning "textbook Japanese" or "good Japanese", and (3) learning conversational Japanese (which, when you have learned the basics, you can move right into listening and speaking practice). (A lot of conversational Japanese is not "grammatically correct," for example, the first greeting everyone learns is こんにちは, which doesn't make any sense when analyzed from a grammatical point of view, but it is what it is, and we have to learn all of the conversational structures.) When you sit down to study Japanese, decide which of these three you will study and only study that one area, do not try to to study 2 or 3 at the same time.
When you are ready to start practicing listening and speaking Japanese, let me know. I have lots of ideas.
Are you ready to do a language exchange, in person or online, with a Japanese person? The way it works is, you spend 20 minutes helping them with their English, then you spend 20 minutes with them helping you with your Japanese. I have lots of ideas on what to do during a language exchange. (I also have ideas on how you can practice listening and speaking Japanese with your English-speaking friends.)
