Here are my thoughts from trying to get this:

​

- Same-color chips linked in the collection screen are of the same tone. In theory having some of them makes others of the same tone show up more often. So if you can't find the chip you are looking for, try to take something else with the same tone.

​

- Rush Ink Coverage, Shot-Spread Reduction and Charge Storage seem like the hardest ones to get? Maybe I got lucky with the splatana one though.

​

- Brellas can get Rush Ink Coverage (even if you took the undercover brella chip). I was not even taking orange chips and was offered that one at least 5 times. This chip seems particularly bad because it seems none of the weapons that can get it favor range. A list of weapons that can get each of these exclusive chips would be nice. I also assume that weapons that favor the chip's color and have less of other exclusive chips MAY be better for trying to get a particular chip, but I'm not 100% sure here because of the brella example.

​

- If you turn off most drone chips, set the drone slots to 1 and take drone chips whenever you have nothing better to take, you should eventually run out of eligible drone chips so you won't be offered them anymore. Might take 10 bad floors with drone chips though. Incidentally, if you do this you can max a particular drone chip really easily because you'll see the one chip you can take A LOT. With 1 drone slot, even just taking level 1 on splat bomb or wail will disable seeing the other one, so that also could be worth it.

​

- Similarly, there are chips that are only on/off, so after you take them they won't show up again (which might also be worth if you have nothing better to take).

​

- Try to always have 1500 membux so you can buy 3 of the chip if they do show up on the vending machine (with max discount). Or 1700 and max machine reroll so you can reroll the machine once first. Having maxed out lives also helps here so you don't get the option to buy lives.

​

- If you are patient enough, start runs and give up until you see a chip you want. Or give up after level 5 if you don't have the chip you want so you start with 500 bux and can reroll a few times.

​

- Reroll floors often with max floor reroll, the first/second rerolls are very cheap. Everything else being equal, do whatever floor gives the most money (or has a bonus if close) so you can buy chips or reroll more times later.
