    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)

Starts making noise if you click on the canvas. Hopefully you can silence it by going left, but no guarantees!

Yes it is :) More fun with a wider frequency range: o.start());c.onmousemove=e=>o.frequency.value=5*e.x

u/pavel

Here, but only problem is that it keeps playing after winning: c.width|=k=300,x.font='20em"',b=frame>>4,m=b&1 for(i=9;i--;)x.fillText("⚬× "[b&2<<i?m^=1:2],580+i%3*k,380+k*(i/3|0))
u/pavel

Oh, nevermind. Its missing boards because it doesn't permute X and O fully for each template.
u/joeytwiddle

Good effort anyway!
