History Main / FrictionlessIce

* It’s not ice, but some kind of frictionless glass surface appears twice in * The Ice Peak of Noltia in ''VideoGame/YsIIAncientYsVanishedTheFinalChapter'' has ice ramps where you must equip the Stone Shoes to walk up them.

* ''VideoGame/MarioAndSonicAtTheOlympicGames'': The DS version of winter olympics has a town mission in which you have to use Mario to get a mini mushroom to traverse a lake without the ice shattering, then build a bridge out of it by pushing blocks in the same style found in the ''Legend of Zelda'' games (only the blocks are frictionless when pushed: Mario himself merely has slighty more slippery controls).

** ''Heroes of Lagaard'' has an entire stratum dedicated to this (Frozen Grounds), including the obligatory "bounce from obstacle to obstacle in a convoluted path to reach the other side" movement puzzles.
** In ''Legends of the Titan'', once you cool down the largest heating scale in a floor in Golden Lair, the whole area will cool down as well, freezing the previously warm water. This frozen water is completely frictionless, both for you and the F.O.E. present. This also applies to the ground ice in [[MiniDungeon Underground Lake]] and [[BonusDungeon Hall of Darkness]] (minus the need of cooling a scale; in fact, at one point you have to do the ''opposite'' by using the Black Flame to warm the areas in order to melt the obstructing ice walls), as well as the Golden Lair once again in ''Nexus''.

* ''VideoGame/SweetHome'' has frictionless ice for some reason but also provides a Pick item that you can use to stabilize your party when they walk over it; otherwise, they'll break party rank and slide across the room helplessly until they reach a damage field depicted by corpses. The Pick, though, was originally used to solve a water puzzle that behaved exactly like the ice. You can also use the Pick to wade through lava safety, another situation just like the water and ice. Yeah.

* A board game called [[http://en.wikipedia.org/wiki/Ricochet_Robot Richochet Robot]] operates on similar rules: The robots (game pieces) are described as lacking brakes or steering, so they must rely on bumping into obstacles (or the other robots) to successfully navigate the board to reach an objective.

* ''Franchise/ShiningSeries''

* ''VideoGame/EpicBattleFantasy4'' has a few of these sliding-block puzzles. Matt comments on how much he hates them.

* There is no ice on the ground in ''VideoGame/IttleDew1'', but blocks/bombs become frictionless when frozen.

* This happens in ''VideoGame/BrainLord'', although you eventually get an item which stops your sliding.
* ''VideoGame/SweetHome'' has frictionless ice for some reason but also provides a Pick item that you can use to stabilize your party when they walk over it; otherwise, they'll break party rank and slide across the room helplessly until they reach a damage field depicted by corpses. The Pick, though, was originally used to solve a water puzzle that behaved exactly like the ice. You can also use the Pick to wade through lava safety, another situation just like the water and ice. Yeah.
* The Ice Park of Noltia in ''VideoGame/{{Ys}} Book I and II'' has ice ramps where you must equip the Stone Shoes to walk up them.

* It’s not ice, but some kind of frictionless glass surface appears twice in ''VideoGame/BoxxyQuestTheGatheringStorm'', first on the Wayback Machine and then in the [[spoiler:Sky Abyss]]. It makes you slide around incredibly fast, and sometimes not in the direction you wanted to go. The prequel, ''[=BoxxyQuest=]: The Shifted Spires'', uses this type of puzzle liberally in its Form Spring dungeon.

* There is no ice on the ground in ''VideoGame/IttleDew'', but blocks/bombs become frictionless when frozen.

* ''VideoGame/CommanderKeen'' has two kinds of ice. One is only a little bit slippery, but the other is so slippery that the only way to change direction on it is with JumpPhysics.

* In the Creator/BrightStarTechnologyInc computer games ''Spelling Jungle'' and its sequel ''Spelling Blizzard'', mud and ice (respectively) function as this. Boulders (in ''Spelling Jungle'') and giant snowballs or ice blocks (in ''Spelling Blizzard'') can be pushed onto them and move the same way; in addition, ice blocks (which the player can ride on if they're in the water) function like this, making getting onto one and staying there a challenge at times.

* Many of ''Franchise/TheLegendOfZelda'' games, though not being direct examples of this trope, will use a less severe version, where the frictionless status applies only to blocks in a block puzzle. Otherwise, ice will merely hinder Link's movement. ''VideoGame/TheLegendOfZeldaTheWindWaker'' averts this trope completely, instead using more realistic friction for ice.

* ''VideoGame/MarioAndSonicAtTheOlympicGames'': The DS version of winter olympics has a town mission in which you have to use Mario to get a mini mushroom to traverse a lake without the ice shattering, then build a bridge out of it by pushing blocks in the same style found in the Legend of Zelda games (only the blocks are frictionless when pushed: Mario himself merely has slighty more slippery controls).

** [[VideoGame/PokemonGoldAndSilver''[=HeartGold=]'' and ''[=SoulSilver=]'']] avert this when a Kimono girl gets her sandals stuck on the ice, causing the player to have to push her off towards the exit.

** ''[=HeartGold=]'' and ''[=SoulSilver=]'' avert this when a Kimono girl gets her sandals stuck on the ice.

* The Flash game ''Dwarf Complete'' has two sections with the SlidingBlock version.

* Three of the puzzles in ''VideoGame/ProfessorLaytonAndTheDiabolicalBox'', as well as two in ''VideoGame/ProfessorLaytonAndTheAzranLegacy'', are based around this concept, where you have to get from point A to point B while dealing with ice that will keep you sliding until you hit a wall (note that this also puts you at the risk of falling into cold water, which will make you fail the puzzle). In ''VideoGame/ProfessorLaytonAndTheMiracleMask'', there are three puzzles where you have to make the Emperor Penguin stop at the central tile of the iceberg, and for that you have to make it clash against the smaller penguins (which, unfortunately for them, will get bounced to the cold water upon clash). Lastly, in ''VideoGame/LaytonsMysteryJourneyKatrielleAndTheMillionairesConspiracy'', there's a series of [[DownloadableContent DailyPuzzles]] where you have to form squared or rectangular groups of penguins by making them slide towards each other in the icy disco stage.

** ''Heroes of Lagaard'' more or less has an entire stratum dedicated to this, including the obligatory "bounce from obstacle to obstacle in a convoluted path to reach the other side" movement puzzles.

* ''VideoGame/RuneScape'' had a cavern filled with these puzzles as part of a Christmas quest.
** In the low-level Dungeoneering dungeons, there are occasionally rooms filled with this, as well as a ''boss battle'' in a room coated in ice. It's not as difficult as it sounds, thankfully. Thankfully diagonals ''do'' exist, or the puzzles would be unsolveable, but the player has to click in the right spot to move along them.

* Ice in ''VideoGame/WarioLand The Shake Dimension'' has no friction, pushed objects like blocks and Wario when frozen will literally slide across the entire area until they hit a wall.
** In ''VideoGame/WarioLand'' games in general, this is the entire point of Frozen Wario. When he gets frozen, he flies backwards like on this type of ice until he hits a wall. It's usually used to bypass spikes and obstacles, since he's invincible when frozen and enemies die on contact, but it's also used as an annoyance in the ice levels.

* It’s not ice, but some kind of frictionless glass surface appears twice in ''VideoGame/BoxxyQuestTheGatheringStorm'', first on the Wayback Machine and then in the [[spoiler:Sky Abyss]]. It makes you slide around incredibly fast, and sometimes not in the direction you wanted to go.
** The prequel, ''[=BoxxyQuest=]: The Shifted Spires'', uses this type of puzzle liberally in its Form Spring dungeon.

* [[http://en.wikipedia.org/wiki/Superfluid Superfluids]], and possibly [[http://en.wikipedia.org/wiki/Supersolid supersolids]], are entirely frictionless. (Of course, if you're in an area cold enough for superfluids to even exist, the lack of friction is the least of your problems.)
* Frequently supposed in kinematics in schools and colleges, since friction would add an unnecessary level of difficulty to a simple physics problem.

* Many of ''Franchise/TheLegendOfZelda'' games, though not being direct examples of this trope, will use a less severe version, where the frictionless status applies only to blocks in a block puzzle. Otherwise, ice will merely hinder Link's movement.
** ''VideoGame/TheLegendOfZeldaTheWindWaker'' averts this trope completely, instead using more realistic friction for ice.
** ''VideoGame/{{Alundra}}'' also has this kind of ice block/character movement separation.
** ''VideoGame/StarFoxAdventures'' had two such puzzles in the Ocean force point temple.

* Three of the puzzles in ''VideoGame/ProfessorLaytonAndTheDiabolicalBox'' are based around this concept, where you have to get from point A to point B.

* ''VideoGame/GoldenSun'''s Tundaria Tower and Mars Lighthouse feature this heavily.
** And in ''VideoGame/GoldenSunDarkDawn'', Harapa Ruins and Phantasmal Bog. Also, the green Zol Blocks have no friction when pushed.

* ''VideoGame/EtrianOdyssey II: Heroes of Lagaard'' more or less has an entire stratum dedicated to this, including the obligatory "bounce from obstacle to obstacle in a convoluted path to reach the other side" movement puzzles.
* Frictionless ice makes for the majority of the Waterworks network in ''VideoGame/MegaManBattleNetwork''. Also, in later games in the series, ice panels may appear in battle which cause the slippery-slide effect.
** This makes no sense in battle because [=MegaMan.EXE=] teleports to move anywhere.
* In ''VideoGame/UltimaUnderworld II'', one of the alternate dimensions had large sections of ice that reduced all control and was pretty much a luck-based maneuvering game. You had virtually no control though you could jump in place to reset your momentum (only worked sometimes). If you crashed into the walls at too high a speed, you took damage. In fact, the [[StrategyGuide hint booklet]] you could buy for the game literally referred to it as Frictionless Ice.

* ''VideoGame/{{Bomberman}} 64: The Second Attack!'' has at least one battle arena which has this, yet appears far more sci-fi than a SlippySlideyIceWorld. Even worse, your inertia ''still applies even after hitting a wall or object'', which means you have to cancel THAT out before you can run away from that bomb right next to you!

* ''VideoGame/SoulBlazer'' has this effect. You can cancel the effect by wearing the Mushroom Shoes given to you by a kid you've rescued.
