About This Game

Turn slot-machine luck into stronger defenses

Slot Machine Defence is a defense game about using slot-machine rewards and favorable odds to grow stronger and hold back incoming enemies. Your choices and upgrades turn each opportunity into defensive power. The new main mode and Classic mode share this core concept, with their own combat and progression systems.

IMPACT — A Major Update with a New Main Mode

Experimental game mode
IMPACT is a new game mode currently in an experimental stage. Its gameplay, content, and balance may change with future updates.

A new battlefield. Boulders you aim. Launchers that fight alongside you.
A new main mode has arrived in Slot Machine Defence. Break robot formations with physics-driven combat, customize your launchers, and build lasting upgrades. The original game remains available in Classic mode.

Break the formation with a boulder

Take aim at the approaching robots and fire. The main mode in Slot Machine Defence is a 3D physics defense game built around collisions and knockback. Start with a launcher you control, then build a defensive line where multiple launchers fight alongside you.

Heavy hits. Explosive chain reactions.

Click to fire a boulder, or hold and release for a powerful charged shot. Boulders shove enemies aside and change course as they collide with walls and wreckage. Increase their mass to push deeper into a formation, or take out an explosive carrier to set off a chain reaction among nearby robots.

Read the enemy. Pick your shot.

Small robot swarms, charging attackers, and shielded enemies that deflect frontal boulder hits call for different tactics. Interrupt a charge with a hit, aim around a shield, or unlock an area smash to break up a crowd. Preview the next stage's enemy formation and prepare your defenses before the fight.

From aimed shots to automated firepower

Spend scrap from defeated enemies on damage, reload speed, boulder mass, size, and blast radius. Strengthen the shot you have now, or save for another launcher. Unlock automatic launchers in the skill tree, then spend scrap to deploy up to four. They find their own targets while you line up your next shot.

Learn weapon types such as rapid-fire, siege, and explosive modifications in the skill tree, then equip each launcher. Combine frequent shots, heavy boulders, and impact explosions, and freely swap between the types you have learned during preparation.

Keep your upgrades. Try a new approach.

Clear stages to earn skill points, expand your skill tree, and reassign points to try different combinations. Defeat preserves your scrap, confirmed skills, equipment upgrades, and automatic launchers. Adjust your setup and take another shot at the stage that stopped you.

Classic Mode — Slot Rewards and Weapon Upgrades

The original Slot Machine Defence remains available through Classic mode in the main menu. Spawn and strengthen weapons with a few clicks, then hold back incoming enemies as your weapons attack automatically.

Spin for rewards and turn them into progress

Spin the slot machine to earn rewards and build up your strength. Make use of lucky opportunities and choose upgrades to prepare for the next attack.

Spawn and enhance your weapons

Your weapons attack automatically, but keeping them upgraded remains essential. Enhancement can succeed or destroy a weapon, and there are ways to improve your chances of success or reduce the risk of destruction. Weigh the risks and opportunities as you build your firepower.

Review your stats and plan your next defense

Check your statistics during play or after the game ends. Review your results and consider your upgrades and strategy for the next attempt.
