Brief explanation of what to do.

Screenshot from field #1 - mainly intended for practising.

The tracks option is enabled here and a target is just hit.

Field #3. The last from the demo. Tracks option on.

Field #4. The target and 3 "annoyers" are active here. Will the target be hit before it fades away?

Field #5. A target is hit a few seconds ago. The hit-indicator is already fading.

Field #6. This is the field from the first prototype of Trajektoria.

Ooops, an "annoyer" has just hit the target, thus stealing some hard earned points.

Field #8. Target is active but the particle is too far away. Suggested action: choose a new location.

Field #9. A particle, a maturing target and two "annoyers".

Field #10.

Field #11. Three annoyers active and tracks option on.

Field #12. Three annoyers active and tracks option on. Notice the common starting point.

Field #13. A target is hit a few seconds ago. The hit-indicator is already fading.

Field #14. The tracks option has been on for some time.

Field #15.

Field #16.

Field #17 finished. Clicking the blue arrow loads next field. (Or just click the field anywhere)

Field #18. The (cardoid) trajectory shown roughly has the shape of a heart.

Field #19.

Field #20.

Field #21.

Field #22. The particle seems to be stuck in a fairly stable orbit here. Will it escape?

Field #23. The higher the level the shorter time the target stays active.

Field #24 is completed. No higher levels available.

Well done. You have finished the last field.
