Welcome to the Windows App Store Quiz

Answer: Flaggenraten

"Flaggenraten" is a free game. The computer shows you a flag and the available options (for instance all countries in Africa), and you pick the correct country. There are modules about Africa, the Americas, Asia, Europe and Oceania, but also about the states of the USA and the states (Bundesländer) of Germany.
The game is available in English, German, French, Italian and Spanish. According to the description, it is fit for the age category 3+, but of course players need to know reading.
"Pocket Monster Battle 2" is based upon the Pokemon creatures. Train your Pokemon and fight against other Pokemons to gain power-ups.
"Arkkanoid 8" is a classical ball and brick game. Bounce the ball towards a brick wall, remove the bricks and break out.
"Royal Trouble 2 HD" is a detective type game. Control the newlywed prince or princess, pick up items and solve the puzzles.
I've found all these games in the subcategory Action & Adventure.

Answer: Master of Mind

There are some free Mastermind type games available. "Master of Mind" is recommended for the age group 3+. Six difficulty levels are determined by the number of pegs to guess (four or five) and the number of available colours. The game is available in single player modus and in dual player modus.
Oddly enough, I've found "Master of Mind" at the subcategory Casino Games. The red herrings listed in this question obviously do belong there, but I would be tempted to look for "Master of Mind" in another subcategory - puzzle games, perhaps.

Answer: Treble Cat

"Treble Cat" is an educative game for age 3+. It shows a music notation staff and you need to click at every specified note played. The game speed can be adapted, and you can switch between the full names of the notes (for instance re - mi - fa) or the letter notation (in the same instance: d - e - f).
There is an alternative for studying the bass clef. This alternative is "Bass Cat".
The other games listed above are also in the subcategory Educative Games. The "Alphabet Game Song" is intended to teach your toddlers reading and writing the alphabet.
"Geoquiz" is of course about geography: it shows a famous landmark (for instance the Golden Gate Bridge), and you need to point to it on a map.
"Math & Match" is a classical memory game, but instead of matching identical images you have to match a mathematical operation with its result.

Answer: Pizza Maker

"Pizza Maker" allows you to bake a pizza completely as you like it in three steps. First of all, you need to make the dough by using the classical ingredients as well as some supplementary items. You may for instance mix black olives into the dough.
The second step is to make the sauce and choose the toppings (vegetables, cheeses, seafood, fruit, and candy).
Finally when the pizza is baked, you can decorate it with a funny face. Click on the ingredients you like to use as a nose, a mouth, two eyes or the hair.
You can dream up the wildest combinations. For instance, you could use broccoli and banana on the same pizza.
"Don't Get Angry" is a computerized version of Ludo or Sorry.
In "Kitten Rush" you move a kitty through rush hour, avoiding cars and other obstacles.
"Pony Island" is based upon the "My Little Pony" franchise: build a valley for your ponies, dress them up and have fun.
I've found all these games listed in the subcategory Family and Children.

Answer: Ultima Reversi

"Ultima Reversi" is a computerized version of the board game Reversi (also known as Othello). Each player in turn has to place a new disc in order to "capture" the opponent's discs in between an earlier placed disc and the one the player has just placed. All the captured discs then are turned into the colour of the player who just made his move.
The game ends when none of the players has any legal move to make. Whoever has the most discs of his colour on board, wins.
"Ultima Reversi" is played against the computer, and you can choose between 10 levels for your opponent.
"Hearts Game Deluxe" is the computerized version of the card game. "Freecell HD" is a specific type of patience card game. "Yaht 3D" is a game of Yahtzee (forming combinations with five dice).
All these are listed under the subcategory Card Games and Board Games.

Answer: Treasure Maze

"Treasure Maze" is a classical platform maze game with 32 levels. Collect gems and use weapons on mine guards. Your king can climb ropes or ladders, jump on moving platforms, push barrles or crates, detonate bombs, and strike with battle hammers or axes. Use the gold and gems you've found to buy better weapons or to restore your health. The ultimate goal is a treasure chest hidden at the end of level 32, and you'll need to buy a very expensive key in order to open the chest.
"Fly or Die" lets you navigate a little bird between vertical obstacles.
"FunnyRun" is a 3D maze game. Run and jump platforms and evade Jurassic raptors.
In "Zombie vs Plants" you're a zombie, and you shoot as many plants as you can. Caution: the bullets from your gun are bound to ricochet - use this effect to the fullest.
I've found all these games in the subcategory Platform Games.

Answer: Can You Escape 2

"Can You Escape 2" is a situational puzzle game such as there are several on the market. As far as I know, you don't encounter any enemies or other health hazards in this specific game. Use some of the objects you see, to solve the puzzles and move on to a next room.
Similar puzzle games are "Can You Escape: Island" (with some deadly booby traps) or "Wild West Escape" (including bandits).
"Sudoku Classic" (solving Sudoku puzzles), "Rubik's Cube" (a three-dimensional representation of the original Cube) and "2048" (join tiles with powers of 2 - adjacent identical tiles will multiply) are other free games I've found these games in the Windows App Store under the subcategory Puzzle Games.

Answer: Parking Frenzy

"Parking Frenzy" is not the usual race game. You have to race the clock to find a parking space whilst avoiding any obstacles in your path. But it gets more complicated if the weather is not fine. Unfavourable weather types include fog, storm, autumn (wet leaves on the road) and winter (snow, ice or sleet).
"Car Racing 3D High on Fuel" is a classic racing game.
"Army Truck 2 - Continuum Release" combines racing and shooting.
"Pac Squirrel" is a modern version of PacMan.
I've found all these games listed under the subcategory Racing and Flying.

Answer: Arcane Quest 3

Based upon the table top role playing game of the same name, "Arcane Quest 3" allows you to pick a character and go out to save the world. You can collect coins and you'll have to engage battle to various enemies. The coins you find, allow you to buy better armour and better weapons.
Choose an adventurer and equip your character with basic weapons. Each character has specific strengths and weaknesses, and specific abilities.
Embark on an epic quest. Eliminate various enemies such as trolls and evil wizards.
"Beach Girls Tattoo Salon" lets you try out various tattoos on young girls dressed in swimwear.
"Beach Food Court" is a game in which you have to select several dishes to serve to impatient customers.
In "Baby Adopter", you need to care for a new born baby.
I found all this games in the subcategory Role Playing Games, although I would probably search for the red herrings in the subcategory Simulations.

Answer: 9 Ball Pool

"9 Ball Pool" allows either practicing against the clock (pot all nine balls before time's up) or playing against a human opponent on the same device.
The rules are simple: there are nine balls (numbered from 1 to 9), and you have to sink them all.
One can use chalk to improve the spinning of the cue ball.
"Funky Hoops" is a basketball simulation.
In "Tropical Kong Penalty", you as a soccer player have to shoot penalty kicks at Donkey Kong.

I've found all these games in the subcategory Sports.
