Snail Bob 4: Space Unblocked — Play Free Online

Snail Bob never walks anywhere on his own initiative, and that is the whole game. He crawls forward at a steady pace and does not look where he is going, so the player's job is to clear a path with the mouse: press buttons, pull levers, and stop him before he wanders into trouble. Snail Bob 4: Space, the fourth entry, moves the series onto a space station, and it is a puzzle game about timing rather than reflexes.

The new idea here is gravity. The first level introduces a purple button that flips gravity, so Bob ends up walking along the ceiling instead of the floor. Once that trick is on the table, every room becomes a question about which surface Bob should be on and when the flip should happen. The game has 25 levels and 75 stars to collect, and it is the original Flash release running through Ruffle, so it plays in the browser with nothing to install.

If you came to this site for the first Snail Bob, this is the same kind of slow, tidy puzzling with a different setting and one extra mechanic to think about. Sessions are short, since each level is a single room.

How to play

Everything is done with the mouse or a tap. Click Play, skip the intro screens, and choose level 1. Click the purple button to flip gravity. Click Bob himself to make him stop, and click him again to send him on his way.

A typical level goes like this: watch where Bob is heading, work out which button or object is in the way, and trigger it just before he reaches it. Because he keeps moving, you are always working against a clock that you can pause by clicking Bob, so use that freely while you think.

Tips

• Stop Bob before you try anything clever. Pausing him costs nothing and lets you study the room.
• Before pressing the gravity button, check what he will walk into on the other surface.
• Stars are usually the difficult part of a level, so finish the room once to learn it and then replay it for the stars.
• Try each button once. Seeing what it changes is often quicker than reasoning about it.

Similar games on Snail Bob

Snail Bob 2 and Snail Bob 3: Egypt Journey use the same click-to-help formula in other settings, without the gravity flip. Sides of Gravity is the closest relative to this game's central mechanic. Pull the String and Happy Glass are physics puzzles where you act once and watch the result instead of guiding a character.

It suits anyone who likes thinking through a puzzle at their own pace, on a desktop with a mouse or on a touch screen.
