The SNES version of Mighty Morphin Power Rangers is a side-scrolling action game composed of seven stages, with two different gameplay styles. In the initial five areas, the player controls one of the five original Power Rangers (Jason, Zack, Kimberly, Billy, and Trini) as they're sent to a location that is being invaded by Rita Repulsa's Putty Patrolers. The player begins the area as their selected character's civilian form, who will fight enemies using their unique hand-to-hand fighting style. After reaching a certain point of the stage, the player character will transform into their Ranger form until they defeat the boss at the end of the Area. As a Power Ranger, the player will attack using their character's signature weapon, as well have access to a greater repertoire of special techniques and abilities than their regular counterpart such as body blows and wall jumps. The ranger will also have a special attack that will damage all on-screen enemies at once, but can only be used once until replenished.

In the final two areas, the player will control the Megazord and fight against a giant monster. While controlling the Megazord, the player will have a power gauge below their life gauge that will determine what kind of special attacks the Megazord can perform. Depending on how much the power gauge has been filled, the Megazord can perform from one of four possible special attacks. There are also two-player versions of these Megazord battles accessible via passcodes in which the second player can control the enemy monster.

The seven bosses in the game are all based on villains which were featured during the first season of the series.

• Area 1: Bones
• Area 2: Gnarly Gnome
• Area 3: Eye Guy
• Area 4: Genie
• Area 5: Dark Warrior
• Area 6: Mutitus (second form only)
• Area 7: Cyclopsis (two forms)

The Game Boy version is a side-scrolling action game as well with five levels, each consisting of two segments. In the first segment, the player will control one of the five original Power Rangers as they fight the Putty Patrollers throughout the stage in order to reach their goal. The player can switch between a standard punch attack or a Power Weapon attack that will gradually consume their life gauge when used. When the player reaches the end of the level, they will control Megazord and fight a giant monster. Like the rangers, the Megazord can switch a regular sword attack and a lightning bolt sword attack that will consume a great portion of the life gauge.

The five bosses featured in the game are all recurring villains from the first season of the show, with the exception of King Sphinx (who only appeared in one episode).

• Level 1: Squatt
• Level 2: King Sphinx
• Level 3: Baboo
• Level 4: Goldar
• Level 5: Rita Repulsa

The Sega Mega Drive/Genesis version is a one-on-one competitive fighting game much like Capcom's Street Fighter II, featuring two different game modes, a 1-Player Scenario Mode and a 2-Player Battle Mode. Like most fighting games, the objective is for both players to fight each other until either one drains the vitality of the other. Each character has two basic attacks (normal and fierce), as well as a set of command-based special moves.

In the Scenario Mode, the matches consist of two segments: the player will fight against a regular sized monster as one of the rangers during the first segment and after the defeating the monster the first time, they will battle a giant version of the same. Initially, only the five original rangers and their mecha, the Megazord, are available. After completing the second stage, the Green Ranger will become a playable character as well, who controls the Dragonzord. The scenario mode consists of five stages with the following adversaries in order of appearance.

• Minotaur
• Evil Green Ranger (summons the Dragonzord during the Zord battle portion)
• Madam Woe
• Goldar
• Cyclopsis (a two-part Zord-only battle)

In Battle Mode, the player can choose between the six rangers, the two zords, and one of the four monsters in a standard best-two-out-of-three match. The Megazord, the Dragonzord, and Cyclopsis cannot be matched against any of the six rangers and vice-versa. Additionally, neither player can choose the same character. A special cheat code will allow the player to play as Evil Green Ranger in Battle Mode. Like the Evil Green Ranger the player faces in Scenario Mode, he is identical to the regular Green Ranger with the added ability to use the Sword of Darkness. Unlike the regular six rangers, Evil Green Ranger may be used to fight Megazord, Dragonzord or Cyclopsis.

The Game Gear version is a fighting game that is similar, but not identical to the Mega Drive/Genesis version. In this version, the player has three basic attacks (one which is done by pressing the two action buttons simultaneously), a throw, and three special moves per character. The game consists of three game modes: a single-player story game which features a series of plot-based battles against the computer, a single-player VS. game, and a 2-player Link game in which the player against another player using the link cable. This version received the most praise from fans of the series.

The Story Game consists of seven stages, each consisting of two segments. In the first segment, the player controls a member of the Power Rangers as they fight against a series of Putty Patrols sent in by Rita, as well as occasional encounters with Goldar, before confronting the stage boss at the end. In the second segment, the player will control one of the Zords and fight a giant version of the stage boss. Only Stage 4 deviates from this format by having the Zord segment occur before the Ranger segment. Initially only the five original Power Rangers are available at the start, along with the Megazord. After defeating the Green Ranger in Stage 4, he will reform and join the other rangers as a playable character, bringing with him the Dragonzord, which can be used during the giant monster segments in place of the Megazord. The player can also use the Dragonzord Fighting Mode as well. The Story Game features the following stages and monsters.

• Stage 1: King Sphinx
• Stage 2: Knasty Knight
• Stage 3: Evil Green Ranger
• Stage 4: Dragonzord
• Stage 5: Shellshock
• Stage 6: Polluticorn
• Stage 7: Goldar and Cyclopsis

In the Vs. Game and Link Game, the player can choose to play as any of the game's sixteen characters fight against an opponent in a round-based match. The six Power Rangers and the Putties cannot be matched against the three Zords and Cyclopsis, while the Dragonzord Fighting Mode cannot be matched against the regular Dragonzord nor against the Megazord. The same character cannot be used by both players. After completing Story Mode, Dream Mode is unlocked as a Vs. option which allows any character or Zord to battle any other character or Zord, including character vs. same character, human-sized character vs. Zord, and Dragonzord Fighting Mode vs. Megazord or Dragonzord.

The Sega Mega-CD version is an FMV adventure game. The game uses footage from the show, and the player must press certain buttons at action sequences. The game features ten levels covering five different episodes ("Day of the Dumpster", "Green with Evil", "The Green Candle", "The Crystal of Nightmares", and "Doomsday").
