Pinq works better when there's data to index
There are no photos of Challenge Round yet, and no named shots, modes or playfield toys on record, so there is not much to show. If you have photos of this game, adding them to OPDB helps.
Pinq is an experimental visual search engine for pinball machines. Machine vision studies the photos on OPDB and writes down what it sees, which becomes the searchable index. The names of shots, modes and playfield toys are aggregated from public rulesheets and guides, with no rules text, descriptions or strategy. Pinq hosts lightweight thumbnail previews only, and every photo, rulesheet, guide and database record is linked at its source. To update a link or ask for a listing to be removed, contact us.
