Much better:

c=document.body;_=`b=[85,1,-1],d=Array(100).fill(0).fill(1,0,40),d[b[0]]=3,c.onpointermove=(e=>{d=d.map(d=>d%2),e=90+e.x/10|0,d[e]=d[e-1]=2}),setInterval(()=>{a=(b[0]+b[1])%10,f=(b[0]+10*b[2])/10|0,e=10*f+a,((b[(d[e]||10<=a||!a)&&1]*=-1)|(b[(d[e]||!f)&&2]*=-1)||10<f)&&!(d[e]=0)||(d[b[d[b[0]]=0]=e]=3,c.innerText=d.map((d,e)=>e%10?d:"\n"+d))},100);`;eval(_);
