Functions & Graphs Game (lines and parabolas)
A maths game to really understand graphs: a function appears drawn (a line or a parabola) and you adjust its parameters — the slope, the y-intercept or the coefficients — until your curve overlaps the target exactly. You see live how each number reshapes the graph, round after round, with the equation updating in real time.

Working out the slope and intercept from a drawn line trains graph reading, a key skill throughout secondary school.
Seeing how m tilts the line, b raises or lowers it, or how a opens and closes the parabola turns abstract formulas into something visual and intuitive.
Going from a curve to its algebraic expression (and back) is exactly what function exams ask for. The game trains it with instant feedback.
"A line appears going up and crossing the Y axis at 2. The student sets slope m = 1 and intercept b = 2, their line overlaps the dashed one and they catch it: y = x + 2."
Prefer to learn without screens? Try this analogue version:
Draw axes with a grid on a sheet.
Draw any line and note where it crosses the Y axis (that is b).
Count how much it rises per step to the right (that is the slope m).
Write y = mx + b and check it by plugging in values of x. With parabolas, try changing a, b and c and watch how it changes.
If you like Function Hunt, these activities work similar skills:
Plotting functions by hand on graph paper is still the best exercise to understand axes, scale and shape.
Move a function's parameters with sliders and watch the graph in real time. Great for exploring families of curves.
A classic for practising the coordinate plane and locating (x, y) points by playing.
