Copperhead Shift

Coins hit the belt fast. You have two bins, one chute, and about a second to decide. Sort by the rule on screen: gold only, silver only, whatever the shift calls for. Wrong bin costs a life. Fake coins go in the chute. Real coins in the wrong chute also cost a life. Hold a coin instead of sorting it and its value climbs the longer you wait. Let go too late and the coin falls anyway. That's the whole risk: bigger payout the longer you hold, zero payout if you're greedy. Clear a wave, pick an upgrade, keep going. A third lane splits the rule in two. Insurance eats one mistake for free. A magnet flags every fake coin before you touch it. None of it slows the belt down for long — waves get faster, rules flip mid-shift, fog rolls in and hides half the coins. Copper marks carry over between runs. Spend them on permanent unlocks: new sorting rules, upgrade slots, a third bin from the start.…
