Inequality Bouncer: Inequalities Game for Grades 6‑8
Work the velvet rope: admit only the guests whose numbers fit the rule.
You are the doorman at a number club. Each night has a rule such as x > 3 or 2x + 3 > 11. Decide fast: admit the guests whose badge numbers make the inequality true and turn the rest away, watching for the sneaky guest standing right on the boundary. After every guest list, graph the solutions on a number line with the right open or closed circle and arrow, or read a graph and pick its inequality. Three levels run from simple inequalities to two-step inequalities that flip when you divide by a negative.

What kids practise
Inequality Bouncer gives students repeated, low-pressure practice with inequalities, number line, graphing solutions, two-step inequalities, and open and closed circles. It is written for grades 6-8, with levels that let younger and older players start at the right difficulty. Every question is generated fresh, so a replay is never the same, and a wrong answer shows the correct one so the round teaches as well as tests.
How it plays
Controls: Tap Admit or Turn away, or press the Right and Left arrow keys (D and A also work). On the number line tap a tick to place the circle, choose Open or Closed and Shade left or right (keys: arrows move, O open, C closed, [ left, ] right), then press Enter to check. Number keys 1-4 pick an answer. P pauses, M mutes.
It works with a keyboard, a trackpad or a touch screen, so it runs on school Chromebooks, tablets and phones.
