SieveHold Bt

Industrial mineral lab horizontal collecting casual game. Mixed colored ore stones fall vertically nonstop from the conveyor belt, drag your sorting sieve only left or right within horizontal range to catch matching target ore for score multipliers. Accidentally catching off-color waste rock consumes one mistake tolerance, full mistake stock restarts your round. Harder rounds speed up ore falling velocity and mix chaotic random color streams that test fast horizontal predictive sliding. Dim metal factory processing plant visuals with horizontal drag sieve mechanics for industrial science casual play.
