Hi Everyone,

![ECS_Challenge_7_THUMB.jpg](https://files.peakd.com/file/peakd-hive/spectrumecons/23tm7G96cwocB66SqBcnRkAnMda7BwtqGaj9zJq5yVMZryUGtavDyHX3UX8kcnZpxbm77.jpg)

Welcome to the Economics Challenge Series for 2023. For the months of July and August, I am running an economics challenge series. The series consists of seven challenges. All seven challenges will commence in July and the results will be published and announced in August. Four of the seven challenges are returning from last year’s Challenge Series. Two are from the monthly contest series and one challenge is completely new. Below are the list of challenges.

-	[Challenge 1: Buying and Selling Game](https://peakd.com/hive-112018/@spectrumecons/economics-challenge-series-challenge-1-buying-and-selling-game)
-	[Challenge 2: Pick-a-Door](https://peakd.com/hive-112018/@spectrumecons/economics-challenge-series-challenge-2-pick-a-door)
-	[Challenge 3: Complements and Substitutes](https://peakd.com/hive-112018/@spectrumecons/economics-challenge-series-challenge-3-complements-and-substitutes)
-	[Challenge 4: Buying and Selling Game (Business Version)](https://peakd.com/hive-112018/@spectrumecons/economics-challenge-series-challenge-4-buying-and-selling-game-business-version)
-	[Challenge 5: Ice Cream Game](https://peakd.com/hive-112018/@spectrumecons/economics-challenge-series-challenge-5-ice-cream-game)
-	[Challenge 6: Game Theory Game](https://peakd.com/hive-112018/@spectrumecons/economics-challenge-series-challenge-6-game-theory-most-or-least)
-	Challenge 7: Even-to-Win

Each challenge could reward winners with as much as 60 Hive Power. The value of the prize will depend on the level of participation. For each new participant, the prize will increase by 5 Hive Power. This will continue until 60 Hive Power is reached (12 participants). The first 12 participants will also receive a 50% upvote from this account. In addition to the prize money, the top few participants will be given points. These points will be used to determine the overall challenge series winner. This winner may receive as much as 80 Hive Power. The value of the prize will equal the sum of the number of participants across all challenges. This will continue until 80 Hive Power is reached.

For more information on the challenge series and the upcoming challenges, I recommend that you read my post [Economics Challenge Series 2023 (Coming Soon)](https://peakd.com/hive-112018/@spectrumecons/economics-challenge-series-2023-coming-soon).

## Welcome to the ‘Even to Win’ Game.

-----

## How to play?

----

The ‘Even to Win’ Game requires participants to select a certain number of boxes (e.g. 7 out of 13 boxes). Each box has been assigned a value. The participant obtains that value if an even number of participants have selected that box. If only one participant selects the box, it does not award that value. If two participants select the box, it offers the value stated in the question. If three participants select the box, it does not award that value. Some boxes have limits to the number of participants that can select them. For example, a box might have a limit of three participants. Once the third participant has selected the box, new participants can no longer select that box. They are limited to the boxes that have not yet reached their limit.

All the information you need to know to play the game is provided in the question; i.e. no external research is required.

All entries must be made in the comments section of this post.

Each account is only permitted one entry.

## Objectives of the game

---

The objective of the game is to obtain the highest total value from the boxes selected. If two participants obtain the same total value, the participant who entered first wins. 

## Game assumptions

----

-	Each box is assigned a value. This value only contributes to a participant's overall score if an even number of participants select that box.
-	Some boxes have participant limits, once the limits have been reached, no other participant can select that box.
-	The participant's order of selection of boxes does not make a difference to the value allocated to the box or the value awarded to the participants selecting that box.

## How are the results of the game determined?

----

The results are determined based on the combined values of the boxes each participant has selected. No results or values need to be generated by any model.

## Challenge Prizes

----

The total prize for this challenge could reach as high as 60 Hive Power. The number of participants determines the value of the prize. For every entry, the prize is increased by 5 Hive Power until a value of 60 Hive Power is reached. The winner will receive 2/3 of the prize and second place will receive 1/3. The first 12 entries will be given upvotes. The winner of this challenge will be given 40 points, second place 20 points, and third place 5 points. These points will be tallied at the end of the challenge series to determine the overall winner.

## Let the challenge begin

----

For this challenge, participants are required to select 7 out of 13 boxes (no more, no less). Each box contains a value. Some boxes have a limit on the number of participants who can select them. These values and limits for each box are as follows:

Box|	Value|	Limit (participant selections)
--|--|--		
Box 1|	17|	Unlimited
Box 2|	38|	2
Box 3|	24|	Unlimited
Box 4|	16|	Unlimited

## More posts

I have several collection of posts. I have organised these collections based on content and purpose.

The first collection contains six collection posts created before PeakD had the collection feature. Four of these posts relate to the core of my content, one of them contains all my Actifit Posts, and one of the them contains my video course ‘Economics is Everyone’.

![Collection_Works.jpg](https://files.peakd.com/file/peakd-hive/spectrumecons/23tv8neL7gM9hnUQPpBYnHHbxxBgxLZxAQ1inmDprTMmdQvr2LjHnRWfkhyjUPRdWySRn.jpg)

The second collection consists of the posts that I consider define my channel. These posts are significant in terms of content as well as how they contribute to the growth of the channel. These posts reveal the most about what I believe in.

![Defining_Post.jpg](https://files.peakd.com/file/peakd-hive/spectrumecons/23uQJe1s4WNdXcuVfyyUrHh7zSHHsX7yk5FLn4BEScGuF1aVhhP8xJDJggdgHZXEhRGnB.jpg)

The third and fourth collection is what I call my ‘Freedom-base Economics living book’. They contain all the posts that support my ideas about the value and power of freedom. Some of these posts explain what we can achieve with freedom and what we need to utilise it. Some of them explain how we are deprived of freedom and how we often give up freedom for security and comfort. The third collection concludes with possible scenarios depending on what we (society) choose to do.
