See it like a Sudoku but then different.
You need a single value in each column and each row. So you got 5 options for your A, then the remaining 4 for your B, and so on. Basically you get an A, B, C, D and E token and for each category you spend one of them.
For example, say you want to play a non-Magical Street Samurai who has a LOT of cyberware&bioware in him.
- You want non-Magic, so you spend your E token on the Magic column which makes you a Mundane.
- You want full cash so you spend your A token on Resources which gives you 450.000 nuyen.
- You decide you want a lot of Skills, so you go B on Skills, this gives you 36 skill points and 5 skillgroup points.
- You decide you want to be physically decent but not too weak mentally so go C in Attributes for 16 Attribute Points (on top of your minimum values.)
- You can now got your D left for Metatype. You can either go Human(3) or Elf(0). Since you're Mundane, your Special attribute points (the (3) or the (0)) would all go into Edge. So either you play a Human with 5 Edge and all attributes on 1 before raising, or you play an Elf with 1 Edge (so not very lucky) who starts at 2 Agility and 3 Charisma before spending your 16 attribute points. Let's say you pick Elf for a bit more solid attributes, at the cost of being less lucky.
So now you're an Elf with 1 Edge, 2 Agility, 3 Charisma, all other attributes on 1, 16 attribute points to spend on attributes, 36 skillpoints and 5 skillgroup points, 450.000 nuyen to spend and no magical ability.
After spending all that you can also spend 25 karma to buy positive qualities (and score bonus-karma for negative qualities), raise a few skills or attributes, or buy a bit more nuyen for chargen. The restrictions and rules for that you can look at when finetuning.
(With this build I'd keep 2 attributes on 1, then buy both those two attributes and Edge to rating 2 with karma. That costs 3x(1+1)x5=30 karma. I'd probably grab Catlike (7 karma), get 25 karma in negative qualities and have 25-30-7+25=13 karma left to spend. Buy 4 skills at rating 1 each for 8 karma, spend the remaining 5 karma on extra contact points and start with 2 7-point contacts.)
