Free to play
This is a free skill-based art-auction prediction game, just for fun. No purchase or payment is required. No money, physical artworks, prizes or anything of monetary value are won or lost. Collection awards are virtual records in your profile only.
Who can play
You must be 16 or older. One account per person.
Making a prediction
Submit your estimate before the deadline shown for each lot. The game displays whether a lot is still open. Predictions made after the deadline are practice only and do not count toward rankings or a season.
Results and rankings
Points reward accuracy against the recorded auction result. The game's scoring guide explains the points. Season rankings use eligible scores for that season. Withdrawn or unsold lots do not award points. Virtual collection awards follow the collection rules shown in your profile.
Fair play
Do not use bots, scripts, multiple accounts or inside information to gain an advantage. ArtAtlas may correct inaccurate auction results and scores or remove accounts that break these rules.
Auction information
Lots, estimates, dates and results come from public auction listings. Auction houses may change, postpone or withdraw a lot. The game is not financial, investment or valuation advice.
No affiliation
The Estimate Game is not affiliated with, sponsored by or endorsed by any auction house, gallery, artist, estate or rights holder unless expressly stated for a sponsored season. Apple is not a sponsor of, and is not involved in, this competition.
