This is the pilot phase dataset for the AllRead study. In the pilot studies of our project, the development of reading skills of children in grades 1–2 was examined using different versions of a digital learning game. The research material contains .csv files compiled from the game log data of the children who participated in the study and the results of the assessment tasks integrated into the game. In addition, the material contains the responses of the guardian survey converted into numerical data (.csv), which mapped the children's demographic background information as well as information about the child's learning to read and any reading difficulties that may have occurred in the immediate family. The first part of the data was collected in a pilot study carried out in 2019, which compared the results of the groups that played the Ekapeli English game and the control group (n 17) playing the GraphoLearn English phoneme game in reading English and Finnish words. The second part of the data was collected in a research intervention carried out in 2020–2021, which tested the functionality of the game Professor Pörröpää and Lukukupla with children in grades 1–2 in 17 classes, who were randomly divided into playing groups and control groups. 223 children participated in the study, of which 124 played the research game and 99 belonged to the control group.
