Instructions
expandGame Goals
In this maths game your aim is to help four waddles of penguins reach the holiday paradise of Summer Isle.
The penguins' vacation migration sees them journey across the perilous Estim Ocean, a vast icy sea patrolled by everhungry killer whales.
Use your estimation and approximation maths skills to position floating icebergs and bounce the penguins safely from glacier to glacier.
How To Play
On each level your task is to get a target number of penguins across the Estim Ocean, so they can continue their quest for a rest.
The penguins start on the left bank, where they've erected a pengopult. Unfortunately, it's not powerful enough to fling the penguins all the way to the safety of the opposite bank.
As a penguin hops into the pengopult, a clock and a maths calculation appears onscreen  when the clock runs out the pengopult launches automatically, and the penguin splashes down at the point corresponding to the answer.
Use your powers of estimation and approximation to work out roughly where the penguin is going to land and place an iceberg. If your iceberg is positioned close enough to the correct answer, the penguin bounces to safety; if not, it tumbles into the whaleinfested waters and is lost.
Game Controls
Position the translucent cursor by moving the mouse left and right, and click to place an iceberg (this also launches the penguin).
You can only place one iceberg at a time (the cursor colour indicates whether you can place an iceberg or not).
Difficulty Settings
You can choose between three difficulty settings: Easy, Medium or Hard
The tougher the setting, the more points you earn, but be warned  you also have less time on the clock, and your iceberg is narrower!
Map
There are four waddles of penguin trying to reach Summer Isle, each a different breed: Emperor, Adelie, Macaroni, and Fairy.
Each waddle follows its own path to the Isle. Each path is a chain of six increasinglytough glacier islands (or levels), each of which must be successfully completed in turn to 'unlock' the next.

Each waddle starts its quest with 20 penguins. Take care as any losses carry over to the next level, making the target tougher to meet. Occasionally you may find eggs which swell the waddle's number.
Scoring
Your overall score is the sum of the highest scores you achieved on each completed level. Your best performance at each level is recorded and retained.
Each time you save a penguin, you are awarded points according to the following formula:
 Base Score
 100 points
 Time Bonus
 40 points per second left on the clock
 Multiplier
 Starts at 1 and increases by 1 each time a penguin is saved; drops back to 1 if a penguin is lost.
For example: say you've just saved your eighth penguin in a row (Multiplier = 8) with precisely 2 seconds left on the clock (Time Bonus = 2 × 40 = 80 points).So the points earned from that penguin are: (100 + 80) × 8 = 1440 points.
Note that as your multiplier increases, the timer decreases too  see how long you can stay in the highscoring zone! The timer resets to its max value if you lose a penguin.

expandBasic Strategies
 Don't waste time (and points!) working out the exact answers
 Although the additions and subtractions may be simple, you almost certainly won't have time to calculate them exactly!
 Try rounding the numbers in the question to one significant figure
 Doing the calculation with the rounded values will be a lot quicker and easier and it will give you some idea of where the "real" answer is. For example, if the question is 6.1 × 4.2, think about 6 × 4 instead. This tells you that that the "real" answer will be near to 24.
 Next, think about whether the answer will be bigger than or smaller than the number you got
 For example, it's clear that 6.1 × 4.2 will be a bit bigger than 6 × 4 and that 5.8 × 3.9 will be a bit smaller than 6 × 4. You should take this into account when you position the iceberg. What about 6.1 × 3.9?
 If you are taking percentages or fractions of numbers then try to visualise how much of the number you need on a number line
 For example, if the question is ⅓ of 74.4 imagine where 74.4 is on the number line and think about where ⅓ of the way to that number is.
Emperor Penguin Path  Addition & Subtraction
 Round whole numbers to the nearest 10
 When dealing with whole numbers you may find that rounding the numbers to the nearest 10 is a useful way to estimate the result.
 It is often easier to add instead of subtract
 When dealing with subtraction it is often easier to add on rather than subtract. For example, 121 − 78 can be estimated as 120 − 80. Starting with 80 you can add on 40 more to make 120. So the estimate is 40.
 Round large numbers to the nearest 100
 When dealing with large numbers that include decimals you can often make a quick estimate by rounding to the nearest hundred. For example, 128.4 + 187.3 can be quickly estimated to 300.
Adelie Penguin Path  Multiplication & Division
 Times Tables to help with Division
 You can use your knowledge of times tables to help with division questions. For example, 35.4 ÷ 6 can be estimated by knowing that 6 × 6 makes 36.
 Take short cuts
 When estimating more difficult divisions you can try to use some short cuts. For example, take 132.5 ÷ 6.23. You can think of this as 12 ÷ 6 to make 2, but the estimate is actually ten times larger, giving an estimate of 20.
Macaroni Penguin Path  Fractions
 Compare the fraction to a half
 When estimating a fraction of an amount, you can often compare the fraction to a half. For example, ⅓ of 41.4 will be less than half of 40. So place the iceberg just below 20.
 Fractions close to 1
 If the fraction is close to 1, for example, ^{8}⁄_{9} of 43, then the answer will be just below 43 – in this case, an estimate around 40 would be good.
Fairy Penguin Path  Percentages
 Divide by 10 to get 10%
 You can find 10% of an amount by dividing the amount by 10. For example, to find 10% of 450, divide 450 by 10 to get 45.
 Use 10% to find other percentages
 Finding 10% first can really help when trying to find other percentages. For example, to find 28.1% of 502, first estimate 10% of 500, which is 50. Then, as 28.1% is nearly 30%, find 30% by working out 50 × 3. An estimate of 150 will be a close approximation.
