This is a brand new logical puzzle app that has been created by Japanese puzzle designers in collaboration with specialist mathematics and science schools.
It has been designed to increase your imagination and thinking abilities to the max!

This puzzle features a maze of calculations and the aim is to calculate the unknown area or length as shown by the question mark by using the other measurements which are provided.
As there are no decimals or fractions involved, the player only needs an elementary school level of mathematics to have a go; specifically, knowing how to determine the area of a rectangle (length × width = area).

Sounds simple enough, right?
Well, have a go at finding out the correct answer which the creators have hidden within each of the levels!
Even if you come across a level that looks difficult, by sharpening your thinking skills you will surely be able to solve it.
And there is nothing like that feeling of accomplishment when you finally solve that difficult puzzle!

In order to prevent puzzles from being solved just by looking at the diagram without performing any calculations, the scale of some of the puzzle diagrams has been adjusted to differ from the actual length or area.

Clear the number of levels shown to unlock more puzzles!

A new puzzle level will be added each day if you meet the conditions.

Conditions
・You have completed the beginner and intermediate puzzles.
・You have also completed the new puzzle.
・A new puzzle will be added once per day when you start the app.
However, you will not receive all the new levels for previous days in which you didn't start the app.

This app has been updated by Apple to display the Apple Watch app icon.

Bug fixed
1.Missing texts displayed
2.Progress data saved

Fun puzzles, but poorly implemented application.

The Area Maze puzzle genre is great, and I like the visual design of the application. But the UI needs work: it's very hard to figure out how to leave notes reliably, and the in-game help never seems to show up.

Illogical numbers, can't solve

The one puzzle I clicked on had a box with an area of 38 square cm...which, if using whole numbers, could only be achieved if the sides were 19 x 2 or 38 x 1. But one of that box's sides was 6 cm. So...good luck figuring out the answer to that one. (It was the first puzzle of level "two stars"). Not worth it- not worth the free.

A fabulous selection of mathematical logic puzzles

My only complaint is there isn't a way of buying more puzzles!

Fireboy and Watergirl in The Forest Temple.No.1: In the first game of the famous game series "Fireboy and Watergirl", the boy and the girl arrive to the forest temple. Fireboy and Watergirl need to go through different levels to find their way out. This two-players game can only be completed if the two players work together in cooperation to find the solution for each room in the temple. Fireboy can not step into water and Watergirl can't step into the hot lava, but they can help each other by pushing buttons and by moving doors.

Fireboy And Watergirl is a free adventure game in which you control two characters in a squad to escape a mysterious forest temple. As a game in the adventure genre, Fireboy And Watergirl promises to bring you very interesting challenges. You need to skillfully combine the couple of fire boy and water girl to quickly discover the mysteries inside the temple and reach the final destination. You must avoid mixing elements together and stay away from green sludge. Play solo or with a friend to solve the puzzles, beat the times, and collect all the diamonds. Try not to let the fireboy fall into the puddle of water and prevent the watergirl from going into the lava spot! Stay away from the green mud and collect all the diamonds to become the master of survival!

Fireboy And Watergirl was developed by Oslo Albet and officially released on December 20, 2018. This first edition is quickly becoming one of the most popular games. With simple controls and gameplay, this game is definitely suitable for everyone. Roaming in the forbidden forest, you will discover the mysteries hidden everywhere. It sounds interesting, but this is not a walk around your house at all. Entering the forest is easy, but getting out of it is not. You must use all your ingenuity and skills to escape as quickly as possible. One of the outstanding features of this game is that you can choose to play alone or with friends. So, what are you waiting for? Invite your buddy to join the adventure today!

Tips and Tricks

Follow the rules to win. Fireboy can collect only the red diamond. The lava pools won't hurt him, but the water puddle will kill him immediately. In contrast, Watergirl can only collect the blue gems, and the lava pools are deadly to her.

Avoid the green mud. The pools of green poison are dangerous to both characters.

Both must survive. Each level is filled with hazardous traps. Only good teamwork will help them get through. They can't make it alone. If any of them dies, you will lose the game.

Preview the terrain before beginning. Studying the level before trying to beat it is a useful tip for you. Take a look at the level, and see what kind of traps are in your way. Observe the danger areas, then start to plan out how to beat the level.

Playing with a friend. This can be a great way to beat all the stages on Fireboy and Watergirl. You control Fireboy while your teammate controls Watergirl. This separates the elements and allows you to concentrate solely on your character.

Which is the first Fireboy and Watergirl?

Fireboy and Watergirl in the Forest Temple is the first game in the famous series.

Can you play Fireboy and Watergirl alone?

Despite the 2-player controls on one keyboard, you can completely complete the game by yourself. Control both Fireboy and Watergirl with both hands at the same time! Why not?

How many levels are there in Fireboy And Watergirl?

There are a total of 32 levels in Fireboy and Watergirl in the Forest Temple. Each level will get harder, so you will need excellent timing and reflexes to escape the temple.
