K40 Online Kalooki
k40online.comK40 Online Kalooki lets up to four people play UK Kalooki together, live, on a phone, a tablet or a computer, and it can be saved to the home screen like an app. It was built for a client, in three days. It has passed a security review, runs on its own server and is backed up every night. It is here because a card game has the same hard parts as plenty of business software: the rules have to be fair, the balances have to be right to the penny, and the owner has to be able to see exactly what happened and when.
The services behind it: Booking and reminder software, Website creation, Website security and Management and maintenance
What this means for your business
The hard parts of a system like this are not the screens. They are being fair, keeping the numbers right and showing the owner exactly what happened. A booking system, a loyalty scheme or a members' area needs the same three things at a smaller scale, and they are far cheaper to design in at the start than to bolt on after something has gone wrong.
What it does for the owner
- Every deal, rule, score and turn timer is handled centrally, not on the player's own phone, so nobody can cheat by tampering with their screen
- Credits handled as carefully as money: every movement is recorded and can never be edited, a stake is held before the game starts, and no game can pay out twice
- A player whose connection drops goes straight back to the same point in the game, with spare time so a short drop does not cost them the hand
- Full owner controls: players, credits, payouts and games, warnings about suspicious play, undoing a payout, a move-by-move replay of every hand, and every balance checked to the penny
- Built for older players: large type, a choice of three looks, adjustable text size, a four-colour deck, keyboard shortcuts, a buzz when it is your turn and a setting to calm the animations
- Works on a phone (sideways too), a tablet and a computer, and there is a demo version you can try straight away
