Guess Chess is available in all countries for adult users only (18 years and above).  


A list of available games will appear on the Guess Chess platform, either on the main page or in the “Play” section. Any user will be able to register at no cost and will be eligible to win cash prizes. However, strictly one user profile only per person is accepted, with a maximum of 2 players from the same IP address.

A user can participate in as many games as they deem appropriate, even if they are being played simultaneously. 

Players can register for games before the start of the game or once it has started. Any user can register at any time during the game.


Once a player is registered in a game, they appear in the leaderboard (which also serves as a registered list) where everyone starts with 0 points. Points are won or lost for hitting or missing predictions.

At least thirty minutes before games are scheduled to begin, registered players’ panels will be activated while they wait for the game to begin. During this time, registered players can send predictions for the first move or sequence of moves that the masters will make. Participants have the option of predicting these moves or move sequences from the beginning of the game right up to its end. A move for either white or black is considered to be a “half move”, and a “full move” consists of two moves: one for white and one for black.

If a user does not submit a prediction before one or several moves are made, their score remains unchanged. This is also the case if, in the process of submitting a prediction, a move is made in the game and the prediction has not reached our system in time.

Users can change their predictions whenever they wish through the “Delete” button on their panel. As might be expected, with this action there is a small risk that the master will make a move at that exact moment and the user’s prediction will therefore not be accepted.

Whether a user submits a sequence or a single move, they can add to their prediction while waiting for the master to move. To do this, the user must press the “Extend” button, which will return the board to the position of their last prediction so that they can continue adding “half moves”.

Simple predictions

In simple predictions (only applies to “half moves”), in the event of a correct prediction, the user will receive as many points as the number of seconds the master has been thinking for since their clock was started for that move. In Rapid and Blitz chess, a multiplier coefficient will be applied.

Tipically, if a classic game may last 220 minutes for the first 40 moves (90+90+20+20) and a Rapid game may last 44 (15+15+7+7), each second of the classic game is rewarded by 1 point and each second of the Rapid game will be rewarded by 5 points (220:44=5).

In case of an incorrect prediction, 50 points are deducted from the user’s score.

The reward of points for every second that the master thinks for is limited to a maximum of 1,800 seconds (30 minutes).

Each successful prediction will be awarded with a minimum of 100 points, regardless of the seconds that the master has thought.

Move sequences

For move sequences, the user will have the option of predicting several consecutive “half moves”. If the user fails in one of the movements, the above mentioned 50 points are deducted for that incorrect prediction and the same for each of the remaining moves of the sequence. The resulting amount will be multiplied by the number of wrong moves in the sequence.

If the entire sequence is correct, the corresponding points for each move will be added and the result will be multiplied by the number of moves that make up the sequence.

For example, in a classic chess game, a player predicts a sequence of 5 moves. The masters, in this hypothetical case, use 100 seconds for the first move, 120 seconds for the second, 130 seconds for the third, 140 for the fourth and 150 seconds for the fifth.

If the user gets the first two correct, but not the third one, they don’t win or lose any points for the first and second moves, but they lose 50 points for the incorrect third move, as well as another 50 for the fourth and another 50 for the fifth (even if the game ends before the number of moves in the sequence was completed). The sum of the 3 penalties (150) is multiplied by the number of failed moves (3), so he’d lose a total of 450 points.

In this case, the user will receive 0 points after the first move and 0 after the second, and will lose 450 after the third, giving a total of -450 points for that prediction.

In the event that he had failed on the first move of that sequence, he would have been deducted 50x5x5= 1250 points.

If the user correctly predicts all 5 moves in that sequence, they receive 100 + 120 + 130 + 140 + 150 = 640 x 5 = 3200 points.

Bonus point moves

For certain moves that are considered important within the games, there will be a bonus of points in case of a successful prediction. These bonuses are applied to both simple predictions and move sequences, with their potential multiplication in the latter case, as detailed above.

The bonuses are as follows:

  • First White move: Always 200 points (exceptionally in this case, regardless of how many seconds the master used to move).
  • First Black move: Always 100 points (exceptionally in this case, regardless of how many seconds the master used to move).
  • From move 36 (“half move” 71) to move 40 (“half move” 80): 50 points for each “half move”.
  • From move 56 (“half move” 111) onwards until the end of the game: 50 points for each “half move”.

If in doubt, you can find a reference table here:

Prediction of the final result of the game

This forecast runs in parallel to the prediction of the moves, both streams of points being added at the end of the game. To be able to add points in the prediction of the result, obviously it will be necessary to get it right. Of course, the earlier it is predicted, the more points will be earned. As follows:

Before starting the game, each result is associated with a certain amount of points. Guess Chess awards more points to the most unlikely results. In total the starting points always add up to 10000. (For example, 2400 the white win, 1600 the draw, and 6000 the black win). During the first 10 moves, on each move the initial amount will be reduced by 5% of the initial figure, until that initial bonus disappears on white’s 11th move.

As soon as the game begins, each ‘half move’ adds 20 points to the provisional balance of the chosen outcome. You can change the outcome at any time, but losing the accumulated points.

If the end of the game coincides with the chosen result, these points are added to the predictions of the moves. If not, nothing is added or subtracted.

You will be able to see at all times in the leaderboard the status of each player’s prediction and the points that he would score if he was right.


In the interest of sporting justice, the integrity of the championships and equal opportunities, the platform reserves the right to take appropriate action and may unilaterally and permanently close a user’s account in the event of flagrant unsportsmanlike conduct. This closure will lead to the disqualification of the user from any championships they are registered in and the loss of any prizes to be awarded (if applicable), which will then be added to the prize pool for the remaining participants.

The following is considered unsportsmanlike conduct:

  1. Collusion of any kind with other users to the detriment of third parties.
  2. Taking advantage in bad faith of any potential fault in the platform, either in isolation or systematically.
  3. Using multiple or third-party accounts for personal use. Each user has their own associated personal data, and impersonating another user could result in the cancellation of all involved accounts.
  4. The participation of any of the championship’s organizing parties. No employee or owner of the platform may participate.  


The distribution of prizes will take place after each competition has been finalized, within a maximum period of 48 hours. This will normally be done much quicker, but in the event of an incident or complaint, records may need to be reviewed.

Those tied for equal points will share the prizes.

Guess Chess will deposit the prize into the user’s money wallet. Before being able to make the first money withdrawal, the account must be verified (providing proof of identity and residence). To reduce transfer costs, only amounts from $64 can be withdrawn. Withdrawal in cryptocurrencies can be requested.

The platform is not responsible for possible price changes with respect to the currency in which the user will finally receive the money.
