Save: Puzzles in progress are automatically saved so you can leave and return to them later. To continue a puzzle in progress simply select the same puzzle on the Jigsaw Explorer website and continue play. Jigsaw Explorer will remember the ten most recently uncompleted puzzles. Puzzles can be saved only if your browser's cookies are enabled and the puzzle is not being played in the browser's privacy mode.

Rotate: Puzzle piece rotation can be enabled by toggling the button with the circular arrow icon on the small center panel that appears when you first load a puzzle. You can toggle rotation on or off after puzzle play has begun by clicking the menu button and selecting "Modify this Puzzle".

When rotation is enabled the puzzle pieces can be rotated with either the mouse scroll wheel or by using the left and right arrow keys. Pieces can rotated on a touch screen by selecting a piece with a tap and then continue tapping the selected piece to rotate it.

Capture and Release: The capture and release feature is a handy method of quickly and efficiently moving multiple puzzle pieces at a time. Use the "Capture and Release" button in the toolbar to toggle in and out of capture mode. Capture pieces by clicking them, or by swiping over them while pressing the mouse button. Release captured pieces by clicking in any open space of the playing area, or by swiping over open space while pressing the mouse button.

All captured pieces can be released in a stack by releasing the first piece and then jiggling the mouse over the piece while continuing to press the mouse button. A stack of pieces can be captured in a similar manner.

Edges Only/Rearrange: The Edges Only button (with the dotted box icon) can be used to hide the interior pieces while you assemble the edge pieces. After the edges are all joined the button can be used to rearrange loose, unmoved pieces towards the perimeter of the playing area. If there are less than 10 loose pieces left to assemble (or if the Shift key is pressed while clicking the button) then clicking the button moves all loose pieces to the perimeter (useful for finding seemingly "missing" pieces that are hard to see).

Note that you can cause any loose puzzle piece to be treated as unmoved (and therefore subject to being rearranged) by moving the piece directly between any two unmoved pieces.

Timer: The timer can be paused by clicking it.

Restart Puzzle: A puzzle already in progress can be restarted from the beginning by clicking the program menu button (leftmost button on the toolbar) and selecting "Modify this puzzle" from the menu. Then select the desired number of puzzle pieces to restart the puzzle.

Fuzzy pieces: If the puzzle pieces appear a little fuzzy or slightly out of focus then your browser is probably applying too much scaling to the page. Try reducing the browser's zoom setting for sharper looking puzzle pieces.

Can you untangle the graph? See if you can position the vertices so that no two lines cross.

Number of line crossings detected: 0

0 moves taken in 0s.

Number of vertices: Generate new, random graph

Highlight non-intersecting lines.

Don't worry, the game only generates solvable graphs! These are known as planar graphs.

About the test

This is a simple tool to measure your reaction time.

The average (median) reaction time is 273 milliseconds, according to the data collected so far.

In addition to measuring your reaction time, this test is affected by the latency of your computer and monitor. Using a fast computer and low latency / high framerate monitor will improve your score.

Scores in this test are faster than the aim trainer test, because you can react instantly without moving the cursor.

This is discussed in further detail on the the statistics page. While an average human reaction time may fall between 200-250ms, your computer could be adding 10-50ms on top. Some modern TVs add as much as 150ms!

Other tools: What's My GPU?

If you want, you can keep track of your scores, and see your full history of reaction times.
Just perform at least 5 clicks and then save.

No sunlight is able to reach this deep.

Many deep-sea creatures cope by creating light themselves - also known as bioluminescence.

Narwhals dive to this depth up to 15 times a day in search for food.

The Japanese Spider Crab is the largest known crab with a maximum leg span of 3.8m.

Coelacanths were thought to be extinct until found alive in 1938.

Leatherback Sea Turtles are the oldest sea turtle species.

Giant Oarfish can grow up to 11m long.

Sixgill Sharks spend the day in deep waters and the night in shallow waters. They can be found all over the world.

Telescope Octopus are almost completely transparent and have unique protruding eyes.

Barreleye Fish have a transparent head that allows their eyes to collect more light.

Black Swallowers can swallow entire fish whole - even those vastly larger than themselves!

Vampire Squids eat marine snow - organic material that falls from shallower waters.

Headless Chicken Fish are sea cucumbers with wing-like fins that allow them to swim.

Colossal Squid are the largest known squid species. They can reach a length of 10 meters and weigh up to 700 kg.

The Orange Roughy can live up to 200 years. Deep sea life often have elongated life spans.

Meals are rare in the deep sea. Deep sea creatures have adapted to this - one Giant Isopod in captivity went five years without eating.

Many deep sea species use the color red as camouflage since it's the first color to leave the spectrum as you dive deeper.

Goblin Sharks are known as "living fossils" because they're the only living species of a lineage that has existed for 125 million years.

Is it a squid, or a worm? It's a worm.

Sea Angels are majestic sea slugs that use wings to propel themselves.

The Scaly-Foot Snail gets its name from the iron plates on its foot and the iron shell it makes out of Iron Sulphide.

Anglerfish have a large bioluminescent lure used to attract prey in the darkness.

Giant Tube Worms get their nutrients from hydrothermal vents.

Hydrothermal vents are formed from seawater passing through extremely hot volcanic rocks. They release heavy metals that are toxic to most animals.

But even in those extreme conditions specialized life finds a way to survive.

Yeti Crabs live on hydrothermal vents.

This is the average depth of the ocean.

But in some places it goes deeper.

Cuvier's Beaked Whales are the deepest diving mammals.

On April 14th, 1912 the Titanic sank to its final resting place at a depth of 3,800 meters.

This is the deepest point of the Manila Trench in the South China Sea.

Patagonian Toothfish have antifreeze proteins in its tissues to prevent freezing in sub zero temperatures.

Megamouth sharks are one of the largest growing shark species with some reaching 7 meters long.

The temperature here is near freezing and very few animals can survive the extreme pressure.

This shark takes cookie-shaped chunks out of its prey.

You have scrolled the height of Mount Everest.

Comb Jellies have been around for 500 million years. Despite looking like jellyfish, they are not closely related.

This is the lowest point of the Puerto Rico Trench.

This is the deepest point of the Java Trench in the Indian Ocean.

The USS Johnston sank in WWII and is the deepest shipwreck ever found.

More people have been to the Moon than the Hadal Zone.

Most of the Hadal Zone takes place in deep sea trenches.

Deep sea trenches form by a process called "subduction" where the Earth's tectonic plates meet and push together.

The deep sea can be a lonely place.

Life here is sparse - the extreme conditions make survival difficult.

But still not impossible.

So little is known about life in these deep environments. Almost every expedition uncovers something new.

Many probes and submarines have been lost trying to reach the deepest parts of the ocean.

On January 23rd, 1960, about 9 years before the moon landing, humans went where they never had before.

Two men, Jacques Piccard and Don Walsh, onboard the submarine Trieste slowly descended into the Mariana Trench.

Their goal was to reach The Challenger Deep - the deepest point in the ocean.

The submarine used a re-breather system that would later be used in spacecraft. There was barely enough space inside the pressure sphere for both of them.

The immense pressure of the deep sea means any mistake would mean certain death.

During the descent, one of the window panes cracked and shook the entire vessel.

Nevertheless, they continued.

Even at these unfathomable depths, Jacques and Don could still see life out the window. Life can survive unimaginable environments.

After 4 hours and 47 minutes of anxiety and claustrophobia...

They succeeded and became the first humans to reach the deepest point in the ocean.
