About this game

Four legs. Real physics. One way up.

4D Lotto is a physics climbing game set inside a giant industrial shaft. You control a small robot spider with four telescopic legs. Shoot them at walls, ceilings, beams and moving platforms, pull yourself up, swing with momentum and leap across gaps. Every move is driven by real physics: gravity, inertia, momentum, collisions and bounces.

CLIMB HAND OVER HAND
Tap anywhere to fire the next pair of legs at that point. The front and rear pairs take turns, so you climb in a natural rhythm. Hang from a single pair and you swing like a pendulum. Hook your claws over the edge of a ledge and haul yourself on top. Swipe to let go and leap, then catch a new hold in mid-air.

SURVIVE THE MACHINE
• Laser gates that warn you before they fire and cut any leg that crosses them
• Saw blades sweeping across the shaft
• Rotating machines that knock you away and sever your legs
• Cracked plates that collapse moments after you touch them
• Greased panels your claws cannot grip
• A shredder that rises from below in the deeper sectors

CARGO MISSIONS
Every third sector you must deliver a power core. It hangs from your body on a tether, so every jump and swing moves it too. Swing too hard and it slips away. Watch the balance meter and keep it steady all the way to the exit hatch.

COLLECT AND UPGRADE
Gather gears to upgrade your spider in the Workshop:
• Leg Length: reach holds further away
• Grip Strength: hold more load and carry cargo more safely
• Movement Speed: faster leg motors and stronger leaps
Collect coins and unlock seven spider skins, from Brass Classic and Chrome Runner to Neon Circuit and Toxic Reactor.

POWER-UPS
A magnet pulls in gears and coins, a shield absorbs one hit or fall, turbo boosts your motors and your reach, and a repair kit restores an integrity cell.

ENDLESS SECTORS
Every sector is generated fresh, so no two runs are the same. Each one is taller and harder than the last, with more hazards and tighter routes. Checkpoint beacons save your progress inside a sector, and fast, undamaged climbs earn big bonuses.

FEATURES
• Original physics climbing with spring-powered telescopic legs
• Procedurally generated sectors with rising difficulty
• Lasers, saws, rotating arms, collapsing plates and the shredder
• Cargo missions with a live balance meter
• Gears, coins, power-ups and upgrades
• Seven unlockable spider skins
• High score and top-10 runs saved on your device
• Pause at any time, with music and sound settings
• Share the game and rate it from the settings
• Plays fully offline

Shoot your legs, grip the steel and climb.
Shoot telescopic legs, swing with real physics and climb a deadly machine.
