Too Hard Puzzles to Solve :[]
Sometimes there are many puzzles or combination of them which makes player to think a bit out of box. This can frustrate a player or it can be enjoyable as well. But at some points in gameplay, there are many puzzles and without solving you cannot progress in game.
Examples[]
1. Uncharted 4: A Thief's End []
Uncharted 4: A Thief's End is an action-adventure video game with many of puzzles involved from historic era. The game has levels at which the player has to solve a puzzle including many small puzzles in one. This makes the player to think with different perspectives as well as takes too much of time to solve. Sometimes it will be a combination of puzzles which will confuse the player and they will get annoyed to solve it completely. Hence, the player will not complete the gameplay and it will lead to many players argue on the gameplay.
2. Pretty Girls Mahjong Solitaire.[]
Pretty Girls Mahjong Solitaire is a pattern matching puzzle game paired with Japanese girl theme. While the artworks are pretty beautiful, the level generation algorithm is really "weird" (a polite way of saying "retarded"). Sometimes the algorithm will generate some levels that are impossible to pass, and you cannot predict that, nor you can tell that at the beginning of the round. Therefore, sometimes you are just wasting your time trying meaninglessly since there is no way to complete it. This game would be much better if the algorithm is actually working properly.
3. Batman: Arkham Knight[]
In Batman: Arkham Knight the Knightfall protocol is not activated till you complete the game 100% which includes collecting all Riddler's trophies. Some of the trophies are really hard to collect. Therefore the player does not get to experience the full game which may annoy him/her.
4. Final Fantasy XIII-2:[]
In Final Fantasy XIII-2 there is a spot entirely dedicated to incredibly difficult puzzles. These puzzles are not impassable and must be completed in order to progress through the game. They are so difficult that many players result to internet algorithms to solve the puzzle instead of doing it themselves.
5. Year Walk[]
In Year Walk, there is a level, the Huldra Part IV, in which the player need to tell the tone that's in tune from several sounds 5 times consecutively to escape from the fog. If the player picks wrong tone, the puzzle reset and the player needs to do it again from the first one. Even music professionals need training to tell the slight difference between different pitches. As a result, many players find this level unreasonably hard so that they look for answers on the internet or give up playing the game.
