Spatial packing puzzle set before the wagon leaves. Each round presents a set of gear items in Tetromino shapes -- rifles, canteens, bedrolls, tin stars -- that must be fitted into a saddlebag grid before the departure timer runs out. Select a piece, rotate it, tap the grid to place. Maximize the gold value of gear packed across five escalating rounds with more pieces and tighter time pressure. First spatial rotation-and-placement mechanic in the series: first Tetromino-style inventory puzzle, first item-value optimization challenge under timer pressure.

First-person perspective obstacle runner down a canyon. Boulders, tumbleweeds, and cacti loom out of a vanishing-point horizon, scaling up via perspective projection as they close in -- tap left or right to dodge. Five escalating stages ramp speed and spawn rate to a punishing pace. First pseudo-3D depth illusion in the series: perspective math drives every obstacle's screen size and position, with tumbleweed lateral drift, canyon wall silhouettes, and scrolling depth stripe markers.

Frontier shooting gallery where the wind is always working against you. Your crosshair drifts with a sine-wave wind that grows stronger every round -- drag to aim against it, then fire at tin cans on the fence, wanted posters sliding past, and horse riders at full gallop. Six shots per round across five increasingly gusty stages. First ballistic wind-drift aiming mechanic in the series: spring-follow crosshair plus oscillating wind offset forces you to lead the drift and choose your moment.

Turn-based ranch strategy across 10 rounds. Buy land parcels, graze cattle to earn income, defend against drought and rustlers. Two threats are revealed before each round -- plan your two actions around them. Overgrazing earns more but risks drought damage; defending costs an action but shields your herd. First territory-expansion economic strategy in the series: spatial ownership, risk-layered resource management, and a multi-round economic arc with compounding returns.

Watch the distant tribe send a sequence of smoke signals -- short puffs and long clouds -- then reproduce each one by holding and releasing your blanket over the campfire. Hold less than the threshold for a Puff; hold longer for a Cloud. Wind shifts scramble the smoke visually and add urgency. Five rounds with tighter timing thresholds and faster winds. First dual-input pattern generation mechanic in the series: hold duration controls signal type, not button selection.

Top-down demolition derby in a frontier dust arena. Steer with LEFT and RIGHT buttons, BOOST to ram rivals -- but watch your engine heat or you'll stall. Ram all rivals to 100% body damage across three escalating rounds (1, 2, then 3 rivals). First vehicular combat mechanic in the series: offensive ramming vs. defensive dodging, with simultaneous dual-resource drain.

Work the iron through three phases: pump the bellows to heat the bar to the golden zone, then hammer each strike point as the pendulum swings overhead, then plunge into the quench barrel and hold for the perfect temper. Five items to forge -- horseshoe to Bowie knife -- with escalating strike patterns and tighter timing windows. First multi-phase material transformation mechanic in the series: iron glows from black to white as temperature rises.

You're a Pinkerton detective tailing a suspect through a frontier town. Follow without being spotted -- hide behind barrels and wagons when they glance back, collect evidence scattered along the trail, and stay close enough to keep the suspect in sight. Five escalating rounds with faster suspects, quicker glances, and more evidence required. First stealth pursuit mechanic in the series: dynamic NPC awareness with line-of-sight cone, proximity detection, and suspicion meter.

A saloon piano plays you a melody - then leaves gaps where notes should be. Listen, memorize, and fill in the missing notes by tapping the correct piano keys before time runs out. Five rounds with longer phrases, faster tempos, and tighter windows. First melody-completion mechanic in the series: musical phrase-memory meets piano keyboard.

Tap rhythmically to spin your lasso and build angular momentum. Watch the rope expand as it speeds up. Hit the sweet zone - then release at the exact angle to catch a moving steer. Five rounds with faster targets, tighter tolerances, and more catches required. First rotational physics skill-toy in the series: momentum-accumulation + precision-release dual-phase mechanic.

You're an outlaw at a sheriff's checkpoint. Answer the questions, keep your story straight, and ride out free. Pick your words carefully - a contradiction will spike your suspicion. Nine questions across three interrogation stages. The sheriff remembers everything you say. First player-side deception mechanic in the series.

Six outlaws. Six hidden bounties. Five rivals with tells you can read. Bid to win, fold to survive. Each rival has a personality - eager bidders signal high value, patient ones signal true worth, bluffers just want to confuse you. Read the room, claim the right outlaws, and walk out with the biggest bankroll. First hidden-information economic game in the series.

A chain of frontier outposts needs your help. Decode incoming flag arm signals from the sender station, match the positions on your own figure, and relay before the wind breaks the chain. Each round adds more letters and shorter windows. Wind gusts scramble the sender's arms mid-signal. First visual semaphore decoding mechanic in the series.

Thermal scope view of a snake pit. Tap to pin a rattlesnake, drag it to the bag before the pin fades. Tough snakes need a full hold before they lock - release early and they slip free. Diamondbacks need the longest hold and the shortest window to bag. First multi-phase hold+drag mechanic per entity in the series.

Draw a trail through procedurally generated wilderness - mountains, rivers, desert, forest - from camp to goal before supplies run out. Each terrain type costs different supplies per tile. Route threats escalate each round: flood zones triple costs, rockslides block paths entirely, rival wagon trains seal off shortcuts. First player-drawn pathfinding mechanic in the series.

Study the wanted poster - hat, build, what they carry, any distinguishing marks. Then scroll through a crowd of frontier silhouettes and tap the fugitive. Wrong IDs cut your payout by 25% each time. Five rounds with growing crowds and tighter decoys. First visual search mechanic in the series.

Drag a slide-whistle to match a coyote howl frequency shown as a scrolling oscilloscope waveform. Hit three frequency targets in sequence to build the pack's trust and draw them in. Hold steady on each target - drift too far and they flee. Five rounds with tightening tolerances and growing packs. First real-time analog pitch-matching mechanic in the series.

Tilt a gold pan to slosh water and separate heavy gold flakes from lighter gravel, fool's gold, and mud. Drag left/right to control tilt — gold's higher density keeps it in, everything else washes out. Tap claim jumpers before they steal your nuggets. First fluid/particle simulation in the series: density-stratification physics, three-round escalation.

Intercept gang telegraph transmissions and decode the signal. Listen for short tones (dot) and long tones (dash), tap to classify each in real time, decode three secret messages, then locate the outlaw hideout on a frontier map. First temporal pattern-decoding game in the series: audio-only mechanic, three-round decode-and-identify structure.

Swing between fence posts as floodwaters rise. Tap to latch your lasso onto the nearest post, pendulum-swing to build height, tap again to release and fly. Miss an anchor and you drop. First grapple-physics survival game in the series: constraint-based pendulum physics, rising water threat, score by height climbed.

Three events, one crowd energy meter, and a multiplier that climbs every time you nail it. Tap the barrels in rhythm, spin and throw a lasso, then hold and release with the horse's bounce. Chain perfects to push the multiplier to 5x -- miss once and it drops back to one.

Navigate a torch-lit canyon maze with nothing but your ears to guide you. A rattlesnake lurks in the dark -- its rattle grows louder and shifts left or right as it draws near. Move slow and deliberate. Rush, and it hears you. Reach the exit before the darkness wins.

Draw paths across the desert basin and watch dust devils follow them in loops, each one playing a note from a pentatonic scale. When paths cross, the music resonates. Landmarks warp the sound -- the mesa deepens a devil's voice, the waterhole makes it wobble. The storm is coming. Compose before it arrives.

You're the auctioneer. Six buyers with distinct budgets and personalities bid on 8 lots of cattle in real time. Watch the room, let the price climb, then tap to call it -- going once, going twice, sold. Wait too long and interest dries up. Call too soon and leave money on the table.

String barbed wire between fence posts to slow and kill rustlers before they reach your cattle. Tap two adjacent posts to connect them -- wires drain rustler HP but take damage over time and break. Five waves of escalating threats. First tower-defense structure in the series.

Physics pinball on a frontier saloon table. Tumbleweeds roll, cactus bumpers fire back, and three WANTED poster targets unlock a big bounty bonus. Tap left or right to flip -- chain bumper hits for multiplied scores. Full ball physics with gravity, spin, and drain.

Turn-based stealth escape from a frontier jail. Pick locks, throw stones to distract guards, slip through shadow zones, and reach the horse outside. Guards patrol with vision cones -- step into the red and it's over. Five escalating layouts.

Drag a glowing brand iron along five cattle-hide templates. Keep the iron in the sweet zone -- too cold leaves no mark, too hot and you burn the hide. Five brands, rising complexity, one shot at the path before the iron cools.

White-water canyon rapids. Steer your raft left and right with momentum -- not lanes. Read the current swirls on the water to predict what's coming, and hold the brake zone to slow down when the channel gets tight. Five rounds, three lives.

A wall of dust has swallowed the road. Your lantern cuts just enough light to see what's coming -- barely. Tap left or right to swerve the stagecoach around boulders that appear out of nowhere. Five rounds, three lives, zero mercy.

A storm tore through the fence and the cattle are heading for the gaps. Tap to set posts, tap again to nail the rail -- but the wind keeps knocking your work loose. Close every gap before dawn.
