Pick your bird's flight line on a grid — its slope (up ÷ across) and start height b — then flap: only the right y = mx + b threads the gaps in the pipes.
Slope Flyer plays like Flappy Bird on a coordinate grid: the bird flies in a straight line, so the child sets that line before each flap — first its slope, by counting how far up and how far across the gap sits (2 up over 4 across = ½), then its start height b on the y-axis, and finally a full y = mx + b that threads two pipes at once. A wrong line crashes into the pipe and the game shows where that line really was ('4 across × 2 = 8 up, but the gap is 2 up'), which targets the common mix-ups of run over rise, ignoring the sign of a falling line, and confusing b with the gap height. A fuse bar adds Flappy pressure while three soft shields restart the sector instead of ending the run. Best for Grades 6–8.
