Matchsticks – a list of apps

Recently I downloaded a couple of matchstick puzzle apps on my android phone and on my ipad. Below you find an incomplete list of android apps with matchstick puzzles.

Here is a short list:

Name	Publisher	Type of puzzles	Remarks
Matchstick puzzle	Uysal Mehmet	Digital Puzzles	Minimalistic interface. It baffled me at first. I didn’t see hints or solutions, but that doesn’t mean they aren’t hidden somewhere.
Puzzles with matches	Celtic Spear	Digital matches, triangles and squares	Well designed interface. Puzzles gradually increase in difficulty. Recommended!
Matchstick puzzles	Gamophonica	Squares	At level 6, I found a symmetrical solution is not recognized. Interface is clear. Same on levels 7 & 8, and probably on subsequent levels too. I informed the publisher and they responded quickly to my email, so I trust this problem will be resolved when you read this (written dec 2016).
Matches Puzzle Game	Bojan Klabjan	Squares, triangles, numerical digits	Original interface. Well designed. Recommended!
Matchstick Puzzle	Alt-y	Digital numbers	Both moving and 1 and 2 matchsticks.
Amazing matchsticks	Network Game&utility	?	I skipped this one, as it asked 4 types of access which I deemed unnecessary
Matches Puzzle 2016	Fitapp Inc	Digital numbers	Both 1 and 2 matches to be moved. If you are stuck, solutions can be bought with in-game money.
Math puzzle with sticks	LogiGames	Digital numbers	Beautiful interface, but I miss a clear indication of how many matches I have to move. Or maybe it is always just 1 match.

I admit I’m not even halfway through the list.

Anyway, here are two puzzles.

Surfaces^**
In the picture below you find 6 matchsticks. If we assume a matchstick is 1 inch long, the enclosed surfce has a size of 2.

Now rearrange the 6 matches into two figures of 6 matchsticks each, in such a way that the surface of one figure is exactly 1.5 time the surface of the other figure.

Remove 4 matches so that you have 5 squares left

This puzzle can be found over and over again in books with matchstick puzzles. Sometimes just one solution is given, though often two solutions are presented. In fact, there are at least 8 different solutions.
Those eight are AFTER discarding rotations and mirror images.
Can you find them all?
