Game Goals

The object of this maths game is to protect Earth from meteors and other space hazards, by using your algebra skills to calculate accurate trajectories for Earth’s surface-to-space missiles.

Unfortunately, you are advised by poorly-educated and argumentative scientists who recommend conflicting trajectory formulae. It is up to you to choose the best formula, and calculate y for x in order to plot waypoints and guide your missile towards its target.

Eliminate all threats and save humanity, using as few missiles as possible.

How To Play

As soon as a meteor is identified it appears on the missile defence screen, and three scientists will each recommend a formula to you. Your first task is to identify a formula that is true for the x and y coordinates of the meteor.

Select the correct formula by clicking on it, and then use that formula to plot two waypoints for the missile. Plot waypoints by positioning your mouse at the appropriate coordinates, and then clicking. The missile will then arm automatically and be ready to fire.

If you miss a meteor by choosing an incorrect trajectory or not positioning the waypoints accurately, the meteor will move closer to Earth before you have the chance to fire again.

Level Guide

Game Controls

You will have three opportunities to destroy each threat before it reaches the Earth.

Select a trajectory by clicking on it. If you change your mind about trajectories, you may simply click another trajectory to cancel the previous selection and any waypoints plotted.

Waypoints are plotted by clicking on a grid reference. They may be cleared by clicking on them a second time.

In Levels 13 and 14, three meteors appear at the same time, and each meteor is labelled with its own flight trajectory. You must first identify the meteor that represents a potential threat to Earth, and click it. Having selected the meteor, you must then go through the usual process of choosing a missile flight trajectory and plotting waypoints towards that meteor.

In Level 18, the terrified scientists are no longer willing to help and you must generate your own formula for the missile trajectory using the trajectory generator.

Operate the trajectory generator by clicking on the arrows to move the values up or down. You must create a formula that is true for both the Earth and the alien world.

Misslie Firing Sequence

The missile tracking system will report on the missile’s trajectory during flight and rate the accuracy of the plotted waypoints as 'Perfect!', 'Great', 'Okay' or 'Bad' in real-time.

If a missile is fired but the player has chosen an incorrect trajectory, then it will miss the meteor regardless of how well the waypoints have been plotted.

If a missile is fired on a correct trajectory but the waypoints have been incorrectly plotted, the missile will deviate from the anticipated trajectory and may miss the meteor altogether.

Scoring

Your overall score is the sum of the highest scores you achieved on each completed level. The formula for the score in a given level is:

For example: say you’ve just completed Level 4 (Level multiplier = 4). You hit the meteor with your second missile (Missile factor = 50%) and with 30 seconds left on the clock (Time bonus = 5 × 30 = 150 points). The missile passed through the first waypoint with a 'Perfect!' rating (Waypoint 1 score = 5000 points) and the second with an 'Okay' rating (Waypoint 2 score = 1000 points). Thus, your total score for the level would be: (5000 + 1000 + 150) × 4 × 0.5 = 12300 points.

So the rule for scoring high is simple: hit first, and hit fast!

Your performance at each level is recorded and retained.
