Math Rescue is an educational, platform game created by Redwood Games and published in 1992 by Apogee Software for the DOS operating system. It was designed by Karen Crowther, who originally designed it in order to entertain her children whilst she was at work. Due to this, the main characters are directly modelled after her son and daughter.

The game was released in three episodes, the first one being a shareware release whilst the final two requiring a payment. In 1993 the game was awarded 'Best Educational Game' at the Shareware Industry Awards.

Plot

A bone-chilling crisis has struck the world! Reports are pouring in from all corners of the globe: Missing numbers!

Numbers were missing from speed limit signs and the frantic highway patrolmen couldn’t stop speeders.
On Wall Street, stock brokers were throwing up their hands in despair. The Dow Jones wasn’t down, and it wasn’t up, it was gone!
Your own mother has closed herself in the bathroom and won’t come out because her paycheck is inexplicably blank.
You start to call your best friend, but the buttons on your phone are blank, and you can’t remember your friend’s number!
Where will it end?!
Glancing out the window, you suddenly freeze with horror. A creature that looks like a giant nose with arms is standing in your driveway!
Its stealing the numbers off your street address and loading them into a robot controlled garbage truck!
Speechless with shock and rage, you point a quivering finger...
Before you can say, “Mystic Intervention”, a huge butterfly appears in the air and dumps a bucket of slime on the nose.
In a flash it disappears!
You have discovered the secret to stopping the number stealers!
Grabbing a nearby garbage can lid for protection, and hoping the butterfly will continue to help you, you embark on your mission to recover the stolen numbers and outwit the mysterious aliens.
Yes, the fate of the world as we know it is in your hands!

Im At the beginning of the game the player was asked to enter their name and to choose whether they were a boy or a girl. The character they control in the game is then a child, either male or female depending on their previous answers. They can move left or right, as well as jump.

The game is split into multiple levels, each of which has 'number blocks' spread around them. In order to progress onto the next level the player must collect all of the number blocks (or just ten in easy mode) in order to complete the key and then reach the exit. In order to collect one of the number blocks the player simply jumps into it, at which point they are transported into a room with numbers blocks 0 to 9 and a mathematical problem written at the top. The player had to work out the solution to the problem and enter the answer by hitting the blocks. Once an answer was entered, correct or not, the player would be returned to the main game. If the player had answered the problem correctly then the number block would disappear, the player is awarded a 'slime' and part of the key would be filled in, however if the player answered the problem incorrectly then the block would remain and a Gruzzle would appear.

Gruzzles are found randomly throughout the game, as well as appearing when a problem is answered correctly. They are the main 'bad guy' of the game, and touching them causes the player to lose a "lid". These lids represent lives and if the player runs out then level had to be restarted, but extra ones could be collected around the levels. Gruzzles can be destroyed using a slime. When the slime button is pressed Benny the butterfly appears above the Gruzzle and drops a bucket of slime on it, making the Gruzzle disappear. This uses up a slime however, and more slime can only be gained by solving problems.

The player was awarded points for most things, from sliming Gruzzles to solving problems. A few ways to gain extra points were included. Toys and food were scattered around each level and were there only for points gaining purposes. Also, if the number blocks were collected in numerical order from zero to nine then bonus points were awarded.

Additionally at the bottom of the game screen would show a sum, for example "12-8=". Around the level are small garbage trucks moving around, each of which has a number on it. If the player touched the garbage truck with the number on it that answered the sum at the bottom of the screen, then the truck would explode, extra points would be awarded and a new sum would be displayed, however if the wrong truck was touched then the player would lose a lid.

Once the player has completed the key they can proceed to the door at the end of the level, which leads on to the next level. Between levels a bonus stage is played, which is a series of rapid-fire math problems that award points, lids and slime but has a short time limit.

Game options

At the start of the game the player chooses a difficulty mode of either easy, medium or hard.

Easy mode was aimed at players aged four to seven. It allowed the player to leave a level after only collecting ten icons, and it also gave the player a slime for every problem they solved. The Gruzzles were not very good at chasing the player in this mode, and did not return when they had been slimed.

Medium mode was aimed at players aged seven to ten. Players had to collect all of the icons on a level in order to move on, but it still gave the player a slime for every problem they solved. The Gruzzles had slightly improved AI in this mode, but still did not return once they had been slimed.

Hard mode was aimed at players aged ten and over. As with medium mode players had to collect all of the icons on a level to move on, but they only received a slime for every other puzzle that they solved. The Gruzzles had significantly improved AI in this mode, and reappeared a short time after being slimed.

Following this the player was able to choose whether they should only be given addition problems, or only be given subtraction problems, or be given a mix of the two. In the second and third episodes multiplication and division problems were also available.

The final decision was on which type of problems the player would encounter. All of the problems were mathematical, however some of them were called 'word problems'. These were written out as full sentences, for example "there are 15 goldfish for sale in a pet store. If Lupe buys 7, how many are left?". A non-word problem would simply be in the form "15-7=?", Players could choose to have no word problems, half word problems or all word problems. They could also choose to skip all of the problems and just play the game, however parents and teachers could choose to permanently disable this option.

Cheats

A few cheats were available for the game. By pressing the letters E, L and M simultaneously the player received extra lids and slime. By pressing the letters P, A and M the player enter a number and move to that level. Also, by pressing the + or - key the game speeded up or slowed down.
