Who said that training multiplication tables can't be exciting?!?!??!!?!
On a planet in a far away galaxy,
you try to fly your way out through a crossfire
in a network of heavily trapped subterranean caves.
Your brave recon ship can only survive that
if you sufficiently power its engines and shields
by solving times tables.
There is also a browser version of TableTunnels (for PC).
It can be found along with other pikido educational games, at:
