First analysis of eight Algol-type binaries: EI Aur, XY Dra, BP Dra, DD Her, VX Lac, WX Lib, RZ Lyn, and TY Tri

• SWASP photometric data were used for a LC analysis of systems never studied yet.
• The second-order effects, like the third light, are also detectable in these data.
• EI Aur and BP Dra contain a large amount of the third light in the LC solution.
• The LC templates were used for deriving the sufficiently precise times of minima.
• XY Dra and VX Lac are probably triples with the periods of 18 and 49 years.

The available photometry from the online databases were used for the first light curve analysis of eight eclipsing binary systems EI Aur, XY Dra, BP Dra, DD Her, VX Lac, WX Lib, RZ Lyn, and TY Tri. All these stars are of Algol-type, having the detached components and the orbital periods from 0.92 to 6.8 days. For the systems EI Aur and BP Dra the large amount of the third light was detected during the light curve solution. Moreover, 468 new times of minima for these binaries were derived, trying to identify the period variations. For the systems XY Dra and VX Lac the third bodies were detected with the periods 17.7, and 49.3 years, respectively.
