Yuyosoft Innovations Inc.

Yuyosoft games include arcade, strategy, role-playing, puzzles and animated action games! Many of these games are based on a completely original concept that you won’t find in any other mobile game.
     Today, so many games look alike, with dark textures, apocalyptic lighting, fancy 3D graphics and physics-based animation. In the case of Yuyosoft, however, we are focused on 2D, colorful cartoon graphics, with simple and addictive gameplay. Interestingly, 2D animation also happens to be a current trend in televised adult animation programs.
     Yuyosoft games are designed and built by a small, experienced team split between Vancouver and Tokyo. Our games are in English, and in many cases, localized into Japanese and Korean as well. Most games are completely free to download and play. Where available, in-app purchases unlock higher levels.
     Whether you are on a mobile phone or tablet, and whether it runs Android or iOS, you can download our games through the App Store and Google Play Store links on this page. We invite you to explore all of our games on this page!

Flying Flags Ultimate

This is the best and most comprehensive among the Flying Flags games on the App Store. This unusual arcade game concept was developed in Vancouver, BC, Canada.

There is a carefully designed learning process at the core of the game. You will recognize, and retain in your memory, the national flags of almost all the countries in the world through repetition, disambiguation and progressive difficulty. And this all happens within the challenging and enjoyable context of an action game.

Tap on the flag that matches the country name at the bottom of the screen while it is visible. Avoid UFOs, as they take away points. So does getting a flag wrong. To move up to the next level, recognize correctly all ten flags at the current level. Do this quickly to receive Time Bonus points. Between levels, there is a mini-game for more bonus points. This reinforces your knowledge of all the flags you have encountered up to that point.

The first five levels are free. Expand your Flying Flags Ultimate through an in-app purchase, to obtain 15 extra levels and exam-like mini-games that reinforce what you have learned. Try to set the high score, as you learn all 190 flags, 20 levels! 

Watching international sporting events on TV will never be the same again, once you know the flags of all the countries!

Alien Racers

Alien Racers is a new concept in mobile games–a puzzle-based racing game! You solve puzzles to advance your racer, but you have to move quickly as your opponents, operated by the game’s AI, are constantly moving toward the finish line.

If you succeed at each mini-game you will move forward, but if you fail, you will take a step backward. The distance you advance (1 to 3 metres) is determined by the difficulty of the mini-game, which is shown on the screen.

Each of the five series features eight races, and the tracks are of varying distances. All eight races of Series A and B are available to play with a free download. With an in-app purchase (US$1.00), you will be able to unlock all races in all series.

All of the racers are aliens who will be familiar to players of other Yuyosoft games, as the same aliens appear in such games as Alien Insurgency, Strange Invaders and Get Aligned.

This game challenges both your puzzle-solving ability and your reflexes, and there are different tracks and awards to keep things interesting.

The earth is being overrun by all kinds of strange aliens. In this exciting shooting arcade game, use eleven different types of guns, each more powerful than the last, to shoot energy spheres at 60 types of aliens. Be careful to aim at only the ones targeted in your current mission.

Each time one of your energy spheres hits an alien, the creature morphs to the next stage in its evolutionary cycle. However, hit a fully evolved alien and it will fall back a stage in its evolution.

When hit, aliens not designated as targets will cause one of your target aliens to slip back a stage, as a penalty, so be careful.

If you convert all the target aliens to their highest evolutionary stage before the timer runs out, you have completed that level, and you will receive a component that goes into the assembly of your next gun. There are ten components for each gun, and as you receive each component, you will see the gun start to take shape.

To fire a gun, press and hold until its charge (shown at the top of the screen) is at the level you want. With a full charge, the energy sphere is released at its maximum speed, whereas with just a tap, the energy sphere moves quite slowly.

In each mission, the aliens may vary, but for that mission and the others at that level, the aliens will move in a characteristic way.

The first 40 missions can be played without limit for free. An in-app purchase gets you the full game, with all eleven guns, 100 missions and 60 aliens. It’s up to you to save the earth, and send them all back to their respective planets.

Chameleon Pattern Match Game

Cute animals surround you in this game, testing your recognition and memory. This is a completely original game concept, developed in beautiful Vancouver, BC, Canada.

Find bubbles of the same color containing the target set of three animals, and press that color at the bottom of the screen to score a point. But beware, a wrong answer causes one point to be subtracted, as a penalty!

Score ten points before the timer runs out, and you will be promoted to the next level. Each level has its own visual obstacles that block the bubbles, often forcing you to make informed guesses with limited information, in order to complete the round within the time limit.

There are five fully working levels, but you can unlock all 30 levels through an in-app purchase.

Drag and drop pieces to complete images, just like a jigsaw puzzle! You have a limited number of turns so move your pieces wisely. If pieces overlap within a cell, or a piece is in the wrong cell, the cell border turns red. If you need a hint, hit the “Check Answer” button, but note that it will cost you 5 turns. There is a small thumbnail of the completed picture at the top of the screen.

As you work your way through the puzzles, the number of turns available decreases, making the game harder. Also, you can earn awards for various achievements, such as solving 3 puzzles in a row.

There are several new photo packs available by in-app purchase, each with thirty themed photographs. These include kittens, puppies, world heritage sites, animals of the world, world travel and great art masterpieces.
A special new in-app purchase is also available, allowing you to use photos from your camera or Photo Roll as puzzles.

Global Spy Game

Your mission: find the spies and items before time runs out!

Your targets are indicated at the top of the screen. Tap the name of a city on the map to move there, and if you find your target spy or item there, tap on the target to capture it.

To finish on time, pay attention to spy intelligence and use the map to find the best route.

Spies move among the cities, but items do not. At higher levels, a spy may escape once captured, and you will need a key to obtain some items. This key is obtained in a similar way to items. The key unlocks a specific item, so nice you have the key, you have to go back to the relevant item and you will be able to pick it up.

Each level has 1-5 spies and items respectively.

Earning a certain score and clearing the level will unlock the next level. In the shop, you can also purchase gadgets to advance faster in the game and even to unlock all levels. However, it is entirely possible to play the entire game without having to buy anything.

This fun game is also good training for your brain — it develops your cognitive skills, including memory, real-time filtering of multiple information sources and efficient route planning.

Go get them, Super Spy!

Strange Invaders

Here’s a game featuring weird and kooky aliens that everybody needs in their life. Playing it strengthens your pattern matching, reaction time and short term memory. Strange Invaders has a retro feel to it, and, well to be honest, it should probably be banned for being so addictive and fun to play!

Winning at Strange Invaders is easy as pie. Simply tap on the flying alien that matches the alien drifting across the bottom of the screen. Avoid touching wrong aliens, though, as that results in a penalty of 10 points. UFOs are even more perilous at minus 30 points.

You can play for free up to level 5, but in-app purchases will unlock an additional 25 levels and new mini-games.

Between levels, there is a mini-game for more bonus points, because who doesn’t like mini-games?! Go, Team Earth!

Try to set the high score, and save the world from the comfort of your armchair. You got this, Supreme Commander, Planet Earth!

Mystery Picture

Can you guess what the scrambled picture is? That’s the basis of this highly unusual game. You have to pick the right answer from a list of six clues. Answer correctly, and the picture is added to your collection.

There are 20 pictures in the free version, and a total of 200 distinct pictures if you make an in-app purchase of the Mystery Picture Full Set expansion pack. Additionally, the other expansion packs (World Animals, Heritage Sites, World Travel and Transportation Vehicles) can be purchased to add a further 100 specialty images each.

If you like puzzles, and have a gift for recognizing pictures cut up into many pieces and jumbled, Mystery Picture is the game for you. Each picture can usually be solved in just a minute or two, and the pieces are always randomly shuffled, so that even with the free version, you will have hours of fun!

Get Aligned

Spooked by the loud voices of humans, the aliens scatter and tumble, using their color camouflage in a desperate attempt to blend into their surroundings. Alas for them, the humans have called upon you to capture all the trembling aliens, and add each one to your collection.

In Get Aligned, take note of the alien in the center of the group. In particular, note the alien’s body color, its background color and which of the four cardinal directions it is facing. If you succeed in getting the other four aliens to exactly mimic the one in the center, you receive that alien for your collection. Collect them all, and save the human race!

You have two weapons, each of which can be in one of two modes. The rotational beam rotates an alien (left and right modes available) and the chromatic laser changes the alien’s color (body and background color modes available). Tap on one of the two buttons at the bottom of the screen to set the currently operational weapon (you can only use one at a time). Tap again to change the mode of that weapon.

Once the mode is set, tap on the alien you are targeting and your selected weapon will take effect. You start with ammunition of five pulses for each weapon, but one pulse is added to the rotational beam, and two pulses are added to the chromatic laser both weapons every three seconds. Don’t forget to keep an eye on the timer, though!

Collection: When you win a round, you capture that alien and it is added to your collection. You can view your collection at any time, using the menu. In the free game, you can collect five types of aliens in six colors, for a total of 30 aliens across three categories. However, if you upgrade to the paid version, there are 30 types of aliens in six colors, for a total of 180 aliens across 15 categories!

City Spy Game

When you play City Spy, you are sent to several different cities. Each city has 22 key locations, of which three are specified as your mission targets.

You can find out the name of each location on the map by tapping on it. However, you can only move to locations that are fairly close to you, so you have to do a bit of route planning to get to your target locations.

Once you enter a target location, you have to answer 5 out of 8 questions correctly within the time given, in order to win a prize. Note that you may already have the prize offered. To finish City Spy completely, you need to collect at least one each of all the available prizes (initially 12 prizes).

If you quit, you don’t get to keep any prizes. If you quit, or successfully complete your mission (collect three items), you will be able to retry the map, or move on to another mission on a different map.

Don’t forget to try our other game, Global Spy! These are the two best spy games for mobile devices.

Good luck City Spy. The Agency is counting on you.
