Tact Challenge is contest for exploring potential of Solidity-like (but for TVM) programming language Tact. It's live now, finishing on 20th of October; it contains five tasks of different difficulty, and solving some of them requires telepathy.

Resolves to number of people with 25 points or more at https://leaderboard.tonsmartchallenge.org/.

I hope that Manifold's mana is not enough incentive to manipulate this market while being disqualified at the contest.
