Sportium

Sportium

Sportium is a one-stroke welding puzzle. Every joint board is a plate of metal

joints linked by weld-lines. Drag the torch from joint to joint and it welds

the line it crosses. The rule is simple and unforgiving: every weld-line on

the board must be welded, each exactly once, without ever doubling back - a

single continuous pass across the whole plate.

Twenty boards climb from a handful of joints to a dense lattice of lines, and

every one of them is built to guarantee a solution exists before it is ever

shown to you - there is always a route, even when it takes a few tries to

find the right starting joint. If the torch runs dry with lines still cold,

that is not a loss, just a wrong turn: reset the plate and strike again.

Clean, fast passes earn full stars and coins for the shop; slower or reset

runs still finish and still pay out, just less. There is no timer pressure

beyond your own par time, no energy meter, and nothing to buy that changes

whether a board is solvable - every plate is fair from the first joint. It is

a quiet, physical kind of logic puzzle: trace the whole circuit, weld it

shut, move to the next plate.
