ClixSense has partnered with multiple companies to monetize and promote systems and services. This translates to ClixSense users as offers. They may include signing-up to a new service, watch a video, install a mobile app, fill out a survey and even playing a game.
Some offers are about buying something, but the majority of offers are completely free.
Completing Offers can help you fulfil the daily checklist. You need to either complete 10 tasks, complete 5 tasks and an offer/survey, or ignore the tasks completely and complete two offers/surveys.
