Unit 3 · Land-Based Empires · c. 1450 – c. 1750
Empire Road — Checkpoint Racer
Race across the gunpowder empires. Every few seconds a checkpoint question appears at the top of the screen and a gate with three answers rises over the road — switch into the lane with the right answer. Right answers earn power-ups; wrong ones cost a strike and show you the real answer.
Switch lanes← →hop one lane per press (A/D, or swipe/tap on touch). SPACEstart. The car drives itself and speeds up the longer you last.
Pick your laneRead the question, then be in the left, middle, or right lane as you pass the gate.
Dodge & collectWeave around parked cars and the odd moving one; grab coin trails as they hop lanes. Pickups: shield, ×2, coin magnet, and the uncommon flying car (10s in the air — no traffic, no gates). Correct answers also earn a power-up; three in a row = a guaranteed shield.
3 strikes · 2 bumpsA wrong gate costs a strike (−1 ♥); lose all three and the run is over. Hitting a car slows you down and leaves you damaged for 10s — hit another while damaged and you crash.
Tip: click the game first so the arrow keys switch lanes instead of scrolling the page.
Checkpoint Log
Every gate you pass logs here — green if you nailed it, red with the correct answer and why if you missed. Review the red ones before your next run.
