Basically, a Screen Test round done on paper. For puzzles with a lot of minor variations, their exact rules on the IB are also given here.
Round note: This round contains 29 puzzles across 29 puzzle types that are more likely to be seen in mainstream puzzle platforms, and are familiar to puzzle enthusiasts regardless of WPC experience. The round contains some observation-based puzzles; please ignore subtle differences due to graphic anomalies or overall distortion.
Points will be deducted for puzzles with limited options, specifically, puzzles numbered 1, 2, 3, 4, 5, 6, 12, 25, 28 and 29. 1 point will be deducted for one error, 3 points for two errors, 6 for three errors, and so on, till 55 points for ten errors. The overall score will not be negative.
The images below represent sheets of paper that were folded and unfolded. The bold grey lines are mountain folds, i.e. folded in, and the dashed grey lines are valley folds, i.e. folded out. Find the image in which the folds are not represented correctly.
The Rubiks cube given below is scrambled with the given set of moves. The moves are defined as per the notation in the diagram, where R represents a clockwise rotation of the right (R) surface and R' represents an anticlockwise rotation of the right (R) surface. Identify the final state of the front (F) surface after the scrambling. The opposite faces of the cube are the same.
The Origami model has been made with a grey sheet of paper (white on the back). The sheet is unfolded. Identify the option that represents the appropriate crease lines after unfolding in which only the essential lines are marked. Essential lines are the ones which are present in the final model and not the intermediate folds used for making the model.
Identify the shape that can be drawn without lifting the pen/pencil or folding the paper, without tracing the same line more than once. The same vertex can be visited multiple times. The ending vertex can be different from the starting one.
Divide the grid into the given tetromino regions (L,I,T,S) along the gridlines. The tetrominoes must be of the same size as depicted and may be rotated but not reflected. Each tetromino shape will be used an equal number of times.
Divide the grid into congruent parts using the given shape. Congruent parts have the same size but may be rotated or reflected. Maximize the number of parts in the given orientation of the shape, i.e. without rotation and reflection.
Identify the set of shapes that can be used together to form the given model. There are no additional parts of the model apart from those visible in either the front view or the back view. Colours are only for the representation of 3D shape.
Identify the correct positions of the jigsaw pieces which fit the shaded cells in the grid below so that they form the given image. The gridlines are only for representing the positions of the pieces. The actual sizes of pieces may vary slightly. Pieces can be rotated but not reflected
5 Partial points will be awarded per correctly identified shaded cell.
Identify the minimum number of swaps required to achieve the given picture. A swap involves the interchanging of two tiles where each tile gets re-scaled to fit the dimensions of the destination tile. The swapped tiles need not be adjacent to each other. Tiles cannot be rotated or reflected.
