An advertisement offering a reward can constitute a unilateral offer that is accepted through the performance of the necessary conditions.
Professor Notes

In 'Carlill v. Carbolic Smoke Ball Co.', the Court of Appeal emphasized the nature of unilateral contracts and the principles of offer and acceptance. The case serves as a pivotal example of how advertisements can constitute binding offers when they invite specific actions, demonstrating that the intention to create legal relations can be assessed from the context of the offer. Importantly, the court highlighted that Carlill's use of the smoke ball in accordance with the advertisement constituted acceptance and fulfilled the terms set forth, thus binding the company under the terms of its own offer.

Moreover, the court's focus on the deposit of £1000 in the bank as evidence of the company's sincere intention to be bound adds an important layer to understanding contractual intention. It directly addresses concerns about whether the advertisement was mere puffery or a genuine offer, reinforcing that sincerity in promises, especially in advertising, can lead to legal obligations.
