Button Game

Wallet restrictions are easily circumvented with burners

Anything with the website can be circumvented by calling contract functions directly

It has to be botproof on the contract level

function play has uint8 input

and require(input == Code);

Code var is random & only retrievable by owner & reset after each button press

website calls contract to get Code var

& makes an autosterogram with Code in it

who has to select from 16x16 grid of numbered buttons

downside is that the ui becomes more cluttered 

alternatively, you could make the claim process more complicated (like finding a hidden code in an autostereogram) and have a claim time limit

for example, the number 157 is hidden in this image

for example, the number 157 is hidden in this image

you'd need a way to generate random int 

this would prevent direct contract interaction automation and website scraping

i have a lot of experience web scraping and this would be a huge pita to automate with a bot

i think it'd be v challenging to decode an autosterogram img
