Basketball is also a very popular spectator sport; Ice Hockey and Volleyball at a level below, then European Handball, Water Polo, and Chess are minorly popular spectator sports
Major clubs -
Jutrzenka - Based in Elbing/Elblag; the club took their name from the Krakow pre-war Jewish club; it's name means "Dawn" in Polish, as the club represents the city's primarily Jewish and Polish inhabitants
Viktoria Allenshteyn - the larger Allenshteyn has two clubs typically in the top division; Viktoria are officially a non-ethnic club but a majority of the fan base are Jewish, due to the city's demographics and the presence of another club:
Warmia Olstzyn - this club was originally a club for the Warmian Poles (Catholic, Polish-speakers in the Allenshteyn/Olstzyn area) but is now popular among many Masurians in the area as well.
Makkabi Kyonigrad & Hakoah Kyonigrad - Two of the nations biggest clubs, they are actually the 'head' of nationwide multi-sport athletic clubs set up in independence. Makkabi traditionally draws from a more religious and rural base while Hakoah from a more urban and secular base, but the two institutions are both based in Kyonigrad.
Baltika Kyonigrad - Another Soviet era club for workers in the fishing, shipbuilding & repair industries that survived because it wasn't affiliated with the KGB or Military (directly, anyway). Again, many of the supporters are Russian
Torpedo Kyonigrad - Torpedo clubs are Soviet-era clubs for workers in heavy industries; automobile and farm equipment manufacture were important in the SSR during Soviet days. As this club was very popular during the JSSR, they managed to stick around after independence. Again, many of the supporters are Russian
Bar Kokhba Nayehoyzen - Based in a rapidly-growing suburb of Kyonigrad, primarily supported by Haredim and the locals
AK Tilzit - multi-ethnic club representing the region, located on the Lithuanian border and although club support includes many Jews and Russian speakers, but also is seen as "the" club for the Lithuanian community
Slavia - Based in Gumbinen in the east of the country, especially popular amongst the the Belarusian and Ukrainian populations
Borussia Inshterburg - multiethnic club in the middle of the country
yo yo clubs:
Spartak Baltishk - the hold over from the Soviet era club representing trade union members; grew in popularity around Baltiysk as the SEZ grew, while simultaneously diminishing in the rest of the country
Mazurka Elk - primarily Masurian club based in the eastern city of Liks/Elk
