How to build from sources

Note: you can download the compiled binaries for Windows at release section, or build docker image by dockerfile, or use compiled image from docker hub: docker pull schwarzlichtbezirk/slotopol and start image as it described.

1. Install Golang of last version and GCC toolchain (tip: for Windows it can be MinGW-w64 distribution from WinLibs).
2. Clone project and download dependencies.
3. Build project with script at task directory.

Project can be built for Windows/Linux/MacOS.

For Windows command prompt:

git clone https://github.com/slotopol/server.git
cd server
go mod download && go mod verify
task\build-win-x64.cmd

or for Linux shell or git bash:

git clone https://github.com/slotopol/server.git
cd server
go mod download && go mod verify
sudo chmod +x ./task/*.sh
./task/build-linux-x64.sh

Then web-service can be started:

slot_win_x64 -v web

The list of all provided games can be obtained by command:

slot_win_x64 list

To find out the list of available RTPs can be with command like this

slot_win_x64 list -i megajack --rtp

See slot_win_x64 list -h with full list of available command line parameters for list-command with filters.

How to test

To calculate nearest precise RTP to given value for any game on embedded reels, you can use the command like

slot_win_x64 scan -g=ctinteractive/luckydollar -r=95.0

Some games algorithms contains Lua-scripts with mathematical RTP calculation without full reels brute force, and returns result on a fly.

You can provide your own reels sets for any game at external yaml-file with same data structure as it in the sources by command

slot_win_x64 -f=/some/path/reeldev.yaml web

To test gameplay workflow, build bot as it described, and run some scripts at script folder of project. See readme for details.

Architecture and logic

Database. Service instance oriented on monopoly usage of it's database. It reads necessary database tables on start and avoids any select requests at all. Then it stores to database only changes and new data (update & insert). Those queries are buffered across API endpoints calls to increase performance with database conversations.

It can be used embedded sqlite database engine, or MySQL, or PostgreSQL databases, its configured at slot-app.yaml settings file,
